Ceramic Manufacturing

Ceramic manufacturing is responsible for fabricating and sintering powdered composites and slurries of inorganic minerals into extremely hard nonmetal parts for a large number of diverse, high-impact applications. Ceramics encompass a broad range of materials and products used for applications from consumer to aerospace, but all ceramics share characteristics of having a crystalline structure, extreme hardness, extreme wear resistance and extreme heat resistance.

Ceramic products can be broken up into four main categories: structural ceramics such as bricks and tiles; refractories for kiln linings, crucibles and other high-heat applications; whitewares such as bone china for dining and other decorative pottery and technical ceramics, also known as engineering ceramics, or advanced ceramics. Advanced ceramics such as silicon carbide are high-performance ceramic parts used in aerospace, nuclear power, bio-medical, military, defense and automotive applications that require exceptional heat resistance or insulation, wear and corrosion resistance. Ceramic manufacturers provide ceramic machining and ceramic grinding services as well as industrial ceramics products such as ceramic armor, ceramic balls, ceramic bearings, ceramic insulators, ceramic rods and heat-insulating ceramic spacers and ceramic tubes.

Among extreme high-impact aerospace and military applications, ceramics have found uses in automotive, power generation, refractory, industrial, food processing, chemical and construction industries. Electric motors use ceramic parts and ceramic magnets to withstand engine heat; wind turbines and jet engines use ceramic blades and rotary bearings; construction industries use ceramic bricks and tiles, and countless industrial heating and cooling applications use ceramic insulators. Bio-medical industries have begun to use ceramic as an optimal material for bone and teeth replacements and prosthetic limbs, and alumina ceramic and boron carbide ceramic plates are used as body armor by U.S. soldiers. Ceramic coatings are used to coat engine components to reduce chemical corrosion or surface temperature of the parts, extending part life. Ceramic insulators, capacitators, magnets and superconductors are known as electrical ceramics. Additionally, there are other types that include ceramic coatings for engine components and industrial wear parts, and chemical and environmental ceramics used as fibers, membranes and catalysts.

Ceramic bearings are extremely hard and are much less dense than other materials, lowering centrifugal force, increasing maximum rotation speed and reducing friction and wear. Ceramics used as bearings, rods, tubes, insulators and other moving parts are nonconductive and in general have a long operating life. Ceramics can be used in environmental applications to absorb toxic materials and decrease pollution or to help with water purification. In the medical field, ceramics are used as bone and teeth replacements as well as blood sugar sensors for diabetics. Trains in Japan use the Meissner effect with ceramic magnets to create levitation. With all these new developments and research, there is little that ceramics may not be used for in the future. Advanced ceramics used in industrial, aerospace and other high-impact applications are made from materials that fall into three categories: oxides such as alumina and zirconia; non-oxides such as carbide, boride, nitride and silicide; and composites of both oxides and non-oxides. These comprise ceramic parts' raw materials, which begin the manufacturing process as fine powders. Other minerals and materials may be added to enhance certain properties. After this, the material is prepped in ceramic manufacturing for forming by adding water or another liquid additive. The slurry or liquid material is then slip cast, pressed, extruded or injection molded into the desired shapes known as greenware, which are then placed in an extremely high heat oven and sintered. The greenware then become rigid products that can then be glazed or further processed by polishing, cutting or machining for advanced ceramic applications. Oxides and non-oxides hold different properties of translucency, hardness, corrosion resistance, heat resistance, wear, weight, microwave absorption and heat insulation. Aluminum oxide and boron carbide, for example, both have qualities of exceptional hardness that are used in armoring applications; boron carbide has a hardness that is close to that of diamonds and is used in body armor.

These materials have a wide range of applications from artificial bones to space shuttle tiles and are desirable because of their many excellent properties: high melting points, oxidation resistance, high hardness and light weight. Many of the desirable properties of various metals, polymers and rubbers are combined in ceramic materials along with properties of intense heat insulation and resistance. Ceramics are often corrosion resistant like stainless steel; some varieties can be harder than titanium; some can be injection-molded or cast like polymers and rubbers, and many are lightweight like aluminum or polymers. Ceramic parts are often more expensive than traditional metal, polymer or rubber materials, an obstacle which has discouraged many engineers from switching to ceramic materials. The long-term benefits of ceramics include reliable part performance, which often triples that of other materials, making ceramic materials a more cost-effective choice in many applications. Ceramic manufacturing does have its limitations, however; unlike polymers, some ceramics cannot be blown or stretched, nor can they be forged and worked like metals, making ceramics susceptible to breakage. It is also difficult to reach high precision tolerances and complex designs with ceramic molding and sintering, although progress is being made to reach tighter tolerances with ceramic manufacturing every day. Advanced ceramics are able to outperform metals in many situations, especially in harsh environments, and are also sometimes able to conduct electricity better than copper. There are many processes that are made possibly solely by ceramics, such as space shuttles and missile cones, which would crack without heat-insulating ceramic casings.

Understanding Types of Ceramics and Their Use in Ceramic Manufacturing

Industrial ceramics play an important role in a variety of manufacturing processes and applications. Typically, people associate ceramics with artistic and decorative pottery made from clay and other composite materials. Industrial ceramics, however, although made using the same materials, serve different purposes. Industrial ceramics are used to provide support to machines or machine parts, and to enhance the yield of manufacturing processes. Nowadays, ceramics are designed and engineered to be industrial-strength products. There have dedicated uses within industrial ceramic manufacturing businesses that supply their products across industries.

Different types of industrial ceramics serve different industries and needs. The following paragraphs describe common types of industrial ceramics and their uses.

Alumina Ceramics

Aluminum oxide is a heavily used material in industrial ceramics. Primarily leveraged in semiconductor compounds and electrical insulation systems, alumina ceramics can be labeled as the one of the most advanced and strongest materials. You can make this ceramic following a number of processes such as is tactic pressing and injection molding. The best feature of these materials is that they provide hard surface and can be given a superior surface finish for their exact application requirement.

More technically, alumina is a material that is considered chemically stable due to its high ionic atomic bonding properties. Being a high ionic material, alumina works as a great electrical insulator. Another advantage of alumina is that it shows a strong resistance to corrosion and damage.

Steatite Ceramics

Made from magnesium silicate, steatite ceramics offer a more advanced option to work as an electrical insulator.Strength; durability and insulation are the prime properties of these ceramics. Because of their outstanding insulation properties, steatite is used in the designing and formation of thermostats commonly used in heating and cooling appliances. The material is a key component in an array of residential and commercial electrical components.

Zirconia Ceramics

Zirconia is the key element in brilliantly designed automotive oxygen sensors and dental ceramics. Having a high resistance to corrosion and breakage, this material is a great choice for the ceramic manufacturing of highly sensitive and well-used components. Wear and abrasion are definitely not concerns for manufacturers who leverage zirconium ceramics.

Silicon Carbide Ceramics

Silicon carbide ceramics are created using the modicums of silicon carbide under high pressure and intensity. The process is also named sintering, and the ceramics that result from this process are very strong and durable. For that reason, these ceramics are used in the production of automotive brakes and clutches.

Mullite Ceramics

Since mullite is a rare material on earth, it is an expensive substitute for commonplace ceramic applications. However, mullite ceramics have no match when strength and high-temperature resistance are required. The material can be used for applications that work within high thermal expansion and low-pressure conditions while needing low thermal conductivity.

All You Need To Know About Ceramic Engineering and Manufacturing

In the simplest terms, ceramic manufacturing is the technique of creating ceramic materials that can support high-tech engineering products and machineries. As their name implies, these items are made from ceramics, usually clay and other non-metallic materials. The material components are mixed with highly pure chemical solutions to meet the strength of the machine they support. A wide variety of glass ceramics used mostly for delicate and designer purposes is also available. During the ceramic manufacturing process, the key concern of product designers is to create something that fits well with the design and engineering of the application. Alumina ceramics are also used in various industrial procedures.

The Surface and Application of Ceramics

Ceramics typically have a crystalline structure. Sometimes, they have anon-crystalline structure, including a hard and smooth or rough surface depending on the application they are being used for. Most ceramics are made to be heat resistant, and are a suitable option for severe processes across industries such as aerospace, mining, and chemical manufacturing. A variation of ceramics can also be seen in packaging and power distribution. These strategically designed ceramics are a component solution for electrical and electronic components.

A Historical View of Ceramics

The concept of using ceramics to meet numerous needs in our daily lives and industrial production is not new. We have been using clay-based pottery for thousands of years as history describes. However, the ceramics that we see in modern times can be traced back to the early Eighteenth Century. It was in1709 when an English businessperson used coke combined with clay to improve the efficiency of smelting process at his production facility. It was the first known and noted evidence of ceramic engineering in recent human history, according to Wikipedia. Ceramics were also largely used in the production of arms and safety equipment during the World War II.

The Ceramic Manufacturing Process

The process of forming ceramics for industrial purposes follows multiple stages that include milling, batching, forming, drying, and burning or firing. The following paragraphs further describe the stages in forming industrial ceramics.

  • Milling - In this process, a raw material is given a desired small shape. Milling itself has different sub-stages, which include destructing, compressing and impacting.
  • Batching - This stage involves exercises like amassing the ingredients according to the pre-defined ceramic preparation method.
  • Mixing -In this step, the ceramic ingredients are mixed through various procedures and machines.
  • Forming - After the base has been prepared, the actual formation of the ceramic components begins. When forming the ceramics, a blueprint is taken into consideration. Nowadays, intelligent machines are used to form the ceramic end product.
  • Drying - After the ceramic has been formed, it is allowed to dry out completely. This process solidifies the shape of the ceramic.
  • Burning - Ceramics are then taken through an extremely high temperature process step conducted within a chimney. This process adds the ultimate strength to the ceramic article.

Manufacturers can ultimately apply a surface layer as the last step in ceramic manufacturing.

  • Alumina ceramic, or aluminum oxide, is an extremely durable and cost effective option used in many industrial and commercial applications.
  • Ceramic armor is an extremely hard nonmetal body having good fracture toughness, extreme wear and corrosion resistance and a high capacity to absorb ballistic impacts.
  • Ceramic balls are rolling spherical elements made of inorganic, nonmetallic materials that are used applications involving rotary or linear motion in addition to a number of other functions.
  • Ceramic bearings are smooth, lightweight and high tolerance, leading to an increased maximum rotational speed.
  • Ceramic bushings are extremely reliable and hardy, and are often made from alumina ceramics or Steatite.
  • Ceramic coatings are, although expensive, able to give coated objects a life of up to 10 times longer.
  • Ceramic composites are raw ceramics mixed with other materials to achieve desired properties. Ceramic composites can be significantly stronger and more resistant to damage.
  • Ceramic grinding is a design and manufacturing process whereby an abrasive is used for material removal, dimensioning and finishing of ceramic components and products.
  • Ceramic insulators are used for a wide variety of applications, because of very good electrical conductivity.
  • Ceramic machining involves the design and manufacture of ceramic precision components.
  • Ceramic manufacturers are companies that make ceramic materials.
  • Ceramic rods are solid, cylindrical ceramic products.
  • Ceramic spacers provide equal and constant spacing between materials or objects.
  • Ceramic tubes are hollow, cylindrical ceramic products, often available with single or multiple bores.
  • Ceramic washers are used for their high abrasion, temperature and corrosion resistance.
  • Industrial ceramics involve the use of non-metallic, inorganic, mineral compounds in the production of large, in size or quantity, ceramics to be used in a wide range of contexts due to their desirable high resistance and insulating qualities.
  • Silicon carbide, or carborundum, is an extremely hard ceramic composed of carbon and silicon atoms bonded in a crystal lattice.
