Graphite has good chemical stability.Through special processing of graphite, has advantages of good corrosion resistance, thermal conductivity, low permeability, a large number of used in heat exchanger, reaction tank, condensation, burning tower, absorption tower, cooler, heater, filter, pump equipment.Widely used in petroleum chemical industry, hydrometallurgy, acid and alkali production, synthetic fiber, paper and other industrial department, can save a lot of metal materials.
For casting, aluminum casting, molding and high temperature metallurgical materials: due to the small thermal expansion coefficient of graphite, and ability to the change of thermal shock, can be used as glass mold, after using graphite black metal casting dimension precision, smooth surface high yield, without processing or slightly processing can use, thus saving a large amount of metal.Production of cemented carbide powder metallurgy process, usually made from graphite material molding and sintering with porcelain boat.Monocrystalline silicon crystal growth of crucible, zone refining containers, stent fixture, induction heater is made by a high purity graphite.In addition of graphite can make vacuum smelting graphite heat insulation plate and the base, high temperature resistance furnace furnace tube, rod, plate, tents and other components.
