As a mineral, natural Graphite is generally divided into flake graphite and aphanitic Graphite. It is usually formed under high-temperature geological conditions and widely distributed in metamorphic deposits. The regional metamorphism of sedimentary rocks rich in organic or carbon matter creates it. It has excellent thermal shock resistance, chemical stability, ultra-high lubricity, low coefficient of thermal expansion, high thermal conductivity, high-temperature resistance, and good electrical conductivity. Crystalline small flakes (or sheets like Graphite) of Graphite appear as isolated, flat, plate-like particles with hexagonal edges if not broken. When broken, the edges may be irregular or angular. Amorphous Graphite: Excellent flake graphite is sometimes called massive amorphous Graphite (or veined Graphite), which occurs in fissure veins or fractures and is characterized by the gigantic plate-like symbiosis of fibrous or needle-like crystalline aggregates, which may be of hydrothermal origin. Highly ordered pyrolytic Graphite refers to Graphite whose angular difference between graphite sheets is less than 1 °. Graphite fiber sometimes refers to carbon fibers or carbon fiber-reinforced polymers.
Artificial graphite: Artificial Graphite, as the name suggests, is Graphite made by synthetic methods. There are many ways to make artificial Graphite. It is common to use powdered high-quality calcined petroleum coke as the primary raw material, add asphalt as a binder, and add a small amount of other auxiliary materials. After mixing various raw materials, press them into shape, and then treat them in a nonoxidizing atmosphere at 2500 ℃ to 3000 ℃ to graphitize them.
