The high temperature resistance of graphite powder is reflected in many fields of industry. Graphite powder can produce high temperature resistant products, refractories, fire-proof materials, etc. Graphite powder can be reprocessed and processed into graphite rods, graphite crucibles, graphite boats, graphite electrodes, graphite brushes, etc. Graphite powder can be used in industrial lubrication, conductivity, refractories, metallurgy and other fields. Ink powder is a kind of multi-purpose industrial material.
