High purity graphite refers to the carbon content of >99.99% graphite, widely used in metallurgical industry of high-grade refractory materials and coatings, military industrial explosive materials stabilizer, light industry, electrical industry pencil brush, industrial battery electrode, additives and catalyst in chemical fertilizer industry.
High purity graphite
Performance: flake crystal integrity, thin and good toughness, excellent physical and chemical properties, good thermal conductivity, temperature resistance, self lubrication, conductivity, thermal shock resistance, corrosion resistance and other properties.
Description: high pure graphite (also known as: flake high thermal conductivity toner) has the advantages of high strength, good thermal shock resistance, high temperature resistance, oxidation resistance, resistance coefficient, corrosion resistance, easy machining and other advantages, is the ideal inorganic non-metallic materials. For the manufacture of electric heating elements, the structure of die casting, high pure metal smelting crucible boat, crystal furnace heater, EDM graphite, sintering mold, tube anode, metal coating, semiconductor technology with graphite crucible, electron tube, thyratron and mercury arc rectifier with graphite anode, grid etc..
The characteristics and application of high pure graphite with high strength, high density, high purity, high chemical stability, high temperature resistance, compact and uniform structure, high conductivity, good wear resistance, self lubrication and easy processing characteristics, widely used in metallurgy, chemical, aerospace, electronics, machinery, nuclear power and other industrial areas. In particular, the large size and high quality high purity graphite, as an alternative material, has a broad application space in the fields of high technology and new technology, and has broad application prospects.

Purification method
It is divided into two categories: one is wet purification, including flotation, acid and alkali, hydrofluoric acid; the two is the purification of the fire, including chlorination roasting and high temperature method
High purity graphite
Widely used in metallurgical industry of high-grade refractory materials and coatings, military industrial explosive materials stabilizer, light industry, electrical industry pencil brush, industrial battery electrode, additives and catalyst in chemical fertilizer industry. High purity graphite after processing, and production of graphite, graphite sealing material and composite material, graphite products, graphite antifriction additives and other high-tech products, various industrial sectors become important non-metallic mineral raw materials.
