Specifications

Graphite silty soft, black gray;Greasy, can pollute the paper.Hardness is 1 ~ 2, along the vertical direction with the increase of impurity hardness can be increased to 3 ~ 5.The specific gravity is 1.9 ~ 2.3.Under the condition of oxygen isolation, its melting point is above 3000℃, which is one of the most temperature-resistant minerals.At room temperature, the chemical properties of graphite powder are stable, insoluble in water, dilute acid, dilute alkali and organic solvents.Materials with high temperature conductivity, can do refractory materials, conductive materials, wear-resistant lubrication 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.
