About Graphite: Graphite is a transitional crystal between atomic crystal, metal crystal and molecular crystal. Soft graphite, black gray, greasy, can pollute the paper. The hardness is 1 ~ 2, along the vertical direction with the increase of impurities the hardness can be increased to 3 ~ 5. The specific gravity is 1.9 ~ 2.3. The specific surface area range is concentrated in 1-20m2/g, under the condition of oxygen isolation, its melting point is above 3000℃, is one of the most temperature-resistant minerals. It can conduct electricity and heat.
Special properties of graphite: high temperature resistance, electrical and thermal conductivity, lubricity, chemical stability, plasticity, thermal shock resistance.
Natural Graphite Powder Usage:
Refractory materials, conductive materials, wear-resistant lubricating materials, corrosion resistant materials, high temperature metallurgical materials, atomic energy and national defense industry, EDM electrode preferred materials, graphite deep processing products to fill plastic products and rubber products. In addition, graphite or light industry glass and paper polishing agent and anti-rust agent, is the manufacture of pencils, ink, black paint, ink and artificial diamond, diamond indispensable raw materials. It is a very good energy saving and environmental protection material.
