Extruded graphite is manufactured in various sizes and shapes. Manufacture of graphite blocks involves several steps, such as preparation of raw materials, forming, sintering and graphitization itself. Crushed material of coke, carbon black, natural graphite and graphite waste is mixed and assorted by the grain size. Later, these materials are connected by admixing of coal tar, pitch and synthetic resin. With regard to shaping, the extruded graphite is, as the proper name expresses, extruded through a hole in the ingot mold in various shapes and sizes. Such semi-products (also called green graphite) are then sintered (carbonized) at temperatures 1000-1200°C without air access, resulting in formation of pores. In order to achieve the required quality of materials, while semi-product is to be at the same time cleaned from residues of binder and impurities, the semi-product is passing through graphitization at temperatures of 2500-3000 ° C, when amorphous carbon is transformed into crystalline graphite. The extruded graphite is specific by its different properties longitudinally and transversely. It is mainly used to produce less exposed graphite products, such as heating bodies, components for industrial equipment and vacuum furnaces for heat treatment of metals, PVD and CVD coating equipment and other structural elements for specialized technologies.
