Characteristics of Isostatic Graphite
Isotropy: There are three main methods of forming carbon and graphite products, namely: hot extrusion molding, such as the production of graphite electrodes for steelmaking; compression molding (including vibration molding) and for aluminum carbon and electric carbon products; isostatic Compression molding. Although the molding methods are different, the molding principles are the same. The direction perpendicular to the pressure surface is different from the direction horizontal to the pressure surface, which is called "anisotropy". This "anisotropy" is beneficial and indispensable to graphite electrodes for steelmaking and brushes for motors. They need this feature. In many other occasions, "anisotropy" is not needed, but "isotropy" is required. So there is isostatic graphite.
