Carbon Graphite

Carbon Graphite

Carbon graphite is the combination of two forms of carbon with coal tar pitch. During the compression molding process, the coal tar pitch holds the two forms together, forming near net shapes. Extreme temperatures then carbonize the coal tar pitch, resulting in a carbon-bound structure that is comprised of both carbon and graphite.

Amorphous carbon is a strong and hard compound that resists wear but produces high friction. Graphite is soft and frail but acts as a lubricant. The combination of the two results in a mixture that is strong and corrosion-resistant with low friction. By producing carbon graphite, the benefits of both carbon and graphite can be utilized.

During carbonization, holes are left in the structure, which provide multiple advantages. One benefit is that the strength and other characteristics of the structure can be enhanced by filling the holes with metals, resins, inorganic salts, or carbon. Another benefit is that higher temperatures can be used to change the entire structure into graphite, allowing for improved functioning in extremely high temperatures and for speed purposes.
