Introduction to Graphite Powder

Graphite powder is a mineral powder mainly composed of elemental carbon, soft in texture, and black gray in color; It has a greasy feeling and can contaminate the paper. The hardness is 1-2, and it can increase to 3-5 with the increase of impurities in the vertical direction. The specific gravity ranges from 1.9 to 2.3. Under isolated oxygen conditions, its melting point is above 3000 ℃, making it one of the most temperature resistant minerals. At room temperature, the chemical properties of graphite powder are relatively stable, insoluble in water, dilute acid, dilute alkali, and organic solvents; The material has high temperature resistance and conductivity, and can be used as refractory, conductive, and wear-resistant lubricating materials.
