High purity graphite

  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.

  Introduction to high purity graphite

  Performance: the flake is of crystalline integrity, thin and good toughness, excellent physical and chemical properties, good thermal conductivity, temperature resistance, self lubrication, conductivity, thermal shock resistance, corrosion resistance and so on.

  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, high purity graphite with large size and high quality, as an alternative material, has a wide application space in high-tech and new technology fields, and has broad application prospects.

  Purification method

  They are divided into two categories: one is wet purification, including flotation, acid-base and hydrofluoric acid; two is the purification by fire, including roasting by chlorination and high temperature.

  High purity graphite applications

  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.
