Graphite powder soft, dark gray; Have greasy feeling, but the pollution of paper. Hardness is 1 ~ 2, along the vertical direction with the increase of the impurity the hardness can be increased to 3 ~ 5. Proportion is 1.9 ~ 2.3. Under the condition of starvation, its melting point above 3000 ℃, is one of the most heat-resistant mineral. Room temperature relatively stable chemical properties of the graphite powder, insoluble in water, dilute acid, dilute alkali and organic solvent; Material has high temperature resistant conductive performance, can be used as refractory materials, conductive materials, wear-resistant lubricating materials.
Graphite powder is a chemical reaction is very sensitive material, in a different environment resistivity he will change, also is his resistance to change, but one thing is not changed, the graphite powder is one of the very good non-metallic conductive material, as long as the object of the insulation inside guarantee graphite powder uninterrupted, like a thin line, also will be powered, but, how much is the resistance value, this value is not an accurate number, because the thickness of graphite powder, graphite powder used in different materials and the environment resistance will be different.
