Graphitization of synthetic carbon

Graphitization processes are carried out at 2600 to 3000°C in inert atmospheres in direct or indirect processes. In direct processes (e.g. Acheson and Castner processes) the carbon articles between the electrodes are heated, either directly or indirectly with resistive materials in between, and the required temperature for graphite formation attained by resistive heating. In indirect processes there is no physical contact between the energy source and the carbon article. 

During graphitization the carbon arlicle.s are heated in inert atmo.sphere.s at 2600 to a maximurn of 3000°C 

Upon graphitization the carbon article attains a graphite-like microstructure. The degree of graphitization depends upon the final temperatures (not the firing time) and the degree of orientation of the. starting material
