Graphite powder is soft and black gray; Hardness is 1 to 2, and the hardness can be increased to 3 to 5 with the increase of impurities in the vertical direction. Weight 1.9 to 2.3. Under oxygen isolation, its melting point is more than 3000, and it is one of the most high-temperature minerals. At room temperature, the chemical properties of graphite powder are stable and insoluble in water, dilute acid, alkali and organic solvents. Materials have high temperature conductivity, can be made refractory materials, conductive materials, wear-resistant lubrication materials. Graphite powder is a chemical reaction is very sensitive material, in different environment resistivity he will change, but also his resistance changes, but one thing has not changed, graphite powder is a very good non-metallic conductive material, as long as the object insulation to ensure that graphite powder uninterrupted, like a fine line, will also power, but the resistance value is how much, This value is not an exact quantity, because the thickness of graphite powder is different, graphite powder used in different materials of the environmental resistance will also be different.
