Specialty graphite mainly refers to high strength, high density, high purity graphite products. Use excellent oil coke as raw material, coal asphalt or synthetic resin as bond agent, it made through raw material preparation, mixing, pressing, crushing, re-mixing, moulding, roast repeatly, soak repeatly, purification and graphitization and machinery processing. It has excellent high temperature resistance, electric and thermal condutivity, lubrication, high temperature performance, anti-chemical corrosion, plasticity, etc. it is the important functional and consumable material, which is widely used in metallurgy, mould, checmial and other industry.
From material structure, specialty graphite could be divided into coarse granules structure, fine granules structure, super fine granules. From moulding method, it could be divided into mould pressing forming specialty graphite, extrusion forming specialty graphite and isostatic pressing specialty graphite. Besides, vibrating forming could be also used for producing specialty graphite.
Specialty graphite is widely used in metallurgical, chemical, oil, mechanical, nonferrous metals, aviation space environmental, nuclear engineering, industry of hi-tech material with higher requirement. Itself has high strength, high-density, high purity, high chemical stability, dense and uniform structure, high temperature resistance, irradiation resistance, high conductive rate, good wear resistance, self-lubrication, etc. It is the irreplaceable material in the production of high technology industry.
