ˎ ̥ 1, as refractory materials: graphite and its products with high temperature, high strength properties, in the metallurgical industry in main used to make graphite crucibles, commonly used in steelmaking graphite as the ingot protectant, metallurgical furnace lining. 2, be conductive material: at the electric industry used to make electrode, the brush, the carbon rods, carbon nanotubes, mercury is the flow of positive, graphite gaskets, phone parts, the television screen coating etc. 3, as wear-resisting lubrication materials: graphite in mechanical industry commonly as a lubricant. Oil often cannot at high speed, high temperature and high pressure conditions used, and the graphite wear-resistant materials can be in (a) **0 ~ ***0 ℃ temperature in high speed of sliding, need not lubricating oil. Many conveying of corrosive medium equipment widely used graphite material made the piston cup, seal and bearing, they don't need to add lubricant during operation. Graphite milk is also many metal processing (wire drawing, laguan) good lubricant. 4, graphite good chemical stability. Through special processing of graphite, has the corrosion resistance, thermal conductivity, permeability low characteristic, is used to make a large heat exchanger, the reaction tank, condensed device, burning tower, absorption tower, cooler, heater, filters, pump equipment. Widely used in petroleum chemical industry, wet metallurgy, acid and alkali production, synthetic fiber, paper and other industrial department, can save a lot of metal materials. 5, for casting, FanSha, molding and high temperature metallurgical materials: because of graphite thermal expansion coefficient of small, and ability to urgent cold urgent hot change, can be used as glass is the molds, use graphite black metal get after casting dimension precision, and the surface is bright and clean high-yield, not processed or make a little processing could be used, thus saving a lot of metal. Hard alloy production and powder metallurgy process, usually with graphite material made of press mould and sintering in porcelain boat. Monocrystalline silicon crystal growth crucible, regional refining containers, stents, fixtures, induction heater is with high purity graphite and processed. In addition graphite also for vacuum smelting of graphite insulation board and the base, high temperature resistance furnace tubes, rods, board, lattice elements such as tent.
