Understanding Graphite: Origins and Applications
The composition of graphite can be tailored to provide specific thermal, electrical, and mechanical properties for various applications. Graphene, a highly crystalline form of graphite, is known for its exceptional electrical conductivity. Large-grain graphite is typically used in electrode manufacturing for steel production. Naturally occurring graphite is formed over millions of years by the solid-phase transformation of amorphous carbon into its crystalline state, under intense heat (750°C) and pressure (75,000 psi).
In the late 1800s, Edward Acheson, founder of the Carborundum Company, accidentally produced synthetic graphite while attempting to create synthetic diamonds. He found that at ambient pressure, amorphous carbon transforms into crystalline graphite when exposed to temperatures between 2300°C and 3000°C.
Graphite possesses both metallic and nonmetallic characteristics. It offers excellent thermal and electrical conductivity, while also exhibiting remarkable resistance to corrosion. These properties enable graphite to perform exceptionally well in harsh environments, particularly in applications involving strong acids with high chloride content, such as hydrochloric acid. Other common applications include heating, cooling, evaporation, and condensation in processes involving nitric, phosphoric, and sulfuric acids.
