Classification:
1. Classified according to the different crystal form: dense crystalline graphite, flake graphite and cryptic graphite;
2. Classified according to the special molding method: isostatic pressure graphite, molded graphite, extruded graphite;
3. Classified according to graphite particles:detail graphite, medium graphite (particle size about 0.8mm ) and electrode graphite (2~4mm).
Characteristics: high temperature resistance,good conductivity and good thermal conductivity,The lubrication performance depends on the graphite scale. The larger the scale, the smaller the coefficient of friction and the better the lubrication performance;Good chemical stability at normal temperature, acid, alkali resistance and corrosion resistance of organic solvent resistance;Strong plasticity, good thermal shock resistance; soft graphite, black gray; greasy, pollute paper;
Application:
1. Metallurgy, steelmaking:refractories, reductants;
2. Electrical industry: manufacturing of electrode, brush, carbon, carbon nanotubes, the positive pole of the mercury current, graphite gasket, telephone parts, TV picture tube coating (conductive material);
3. Machinery industry: made of piston cup, seal ring and bearing, metal processing (wear-resistant lubricating material);
4. The petroleum chemical industry, metallurgy, acid-base production, synthetic fiber (production reactor, heat exchanger, condenser, combustion tower, absorption tower, cooler, heater, filter and pump equipment)
5.   Atomic energy industry and defense industry:neutron moderator, solid fuel rocket nozzle, missile nose cone, parts of aerospace equipment, thermal insulation materials and radiation protection materials;
6. Boiler, bridge, pipe:anticorrosive and antirust;
7. Glass and papermaking:polishing agent and antirust agent;
8. Pencils, ink, black lacquer, ink and artificial diamond, diamond:raw material;
9. Other industries: automotive batteries, composite materials, casting, sand-casting, molding and high-temperature metallurgical materials etc.
