Isostatic graphite refers to graphite materials produced by isostatic pressing. Isostatic graphite is pressed uniformly by liquid pressure during the molding process, and the obtained graphite material has excellent properties. It has: large molding specifications, uniform blank structure, high density, high strength, and isotropy (characteristics and dimensions, The shape and sampling direction are irrelevant) and other advantages, so isostatic graphite is also called “isotropic” graphite.
