The body is a single graphite carbon, graphite, or contain small amounts of impurities such as chemicals and ash graphite packing, graphite can follow graphite carbon content classify graphite, graphite carbon content in accordance with the descending sequence can be divided into high-purity graphite powder graphite, high carbon graphite, carbon graphite and carbon graphite, graphite powder according to this classification can be applied to the requirements of the carbon content of the corresponding high, medium and low industrial areas . Graphite powder can also be classified by particle size, particle size in addition to ordinary graphite powder, graphite powder in the ultrafine particle has a clear classification, graphite powder particle size units are generally expressed in microns, can be divided into fine graphite powder, graphite ultrafine powder, graphite powder and ultra-fine submicron graphite. Black graphite iron equipment, low hardness, a group of very complete cleavage, there are slippery sensation and stained hands. Graphite is formed at high temperatures. Graphite is most common in marble, schist or gneiss graphite manufacturer, is the organic origin of carbonaceous material from deterioration. Seams can be formed by thermal metamorphism of graphite parts. Graphite is a small amount of primary igneous minerals. Graphite is also common in meteorites, usually lumpy, with a certain orientation relationship cube shape composed of polycrystalline aggregates known as cubic graphite.
