Basic introduction of graphite powder

Graphite powder is a kind of mineral powder, the main component is carbon element, it is soft, dark gray; it has a greasy feel and can contaminate paper. The hardness is 1-2, and the hardness can increase to 3-5 with the increase of impurities in the vertical direction. The specific gravity is 1.9 to 2.3. Under the condition of isolating oxygen, its melting point is above 3000℃, which is one of the most temperature-resistant minerals. The chemical properties of graphite powder are relatively stable at room temperature, and are insoluble in water, dilute acids, dilute alkalis and organic solvents. The material has high temperature resistance and conductivity, and can be used as refractory materials, conductive materials, and wear-resistant lubricating materials.
