The production processes for synthetic carbon and graphite materials are equivalent to those applied in the ceramic industry. The solid raw materials coke and graphite are first milled and then mixed with binder pitch in mixers. Afterwards the shaping process such as isostatic pressing, extrusion, vibration molding, or die molding takes place.
The shaped bodies, called “green” material, are then carbonized in an oxygen free environment and graphitized before they can undergo further mechanical processing to be turned into complex shapes. Optional further refinements such as purification and coating e.g. with silicon carbide are possible.
