1, graphite materials can be used as refractory materials: graphite and its products have the properties of high temperature resistance, in the metallurgical industry, mainly used to make graphite crucible, in steel making commonly used as the protective agent of ingot, lining of metallurgical furnace.

2. Graphite material can be used as conductive material: it is used in the electrical industry to make electrodes, brushes, carbon rods, carbon tubes, and the anode of mercury rectifiers, graphite gaskets, telephone parts, and coating of television picture tubes.

3, graphite materials can be used as wear-resistant lubrication materials: graphite is often used as a lubricant in the mechanical industry.Lubricating oil often can not be used at high speed, high temperature, high pressure conditions, and graphite wear-resistant materials can be in the temperature of 200~2000 ℃ at a high sliding speed, without the use of lubricating oil.Many equipment for conveying corrosive medium are made of graphite material, such as piston cup, sealing ring and bearing.Graphite emulsion is also a good lubricant for many metal processing (wire drawing, tube drawing).

4, graphite materials can graphite has good chemical stability.After special processing of graphite, corrosion resistance, good thermal conductivity, low permeability characteristics, a large number of heat exchangers, reaction tank, condensers, combustion tower, absorption tower, cooler, heater, filter, pump equipment.Widely used in petrochemical industry, hydrometallurgy, acid and alkali production, synthetic fiber, papermaking and other industrial sectors, can save a lot of metal materials.

The varieties of impervious graphite contain different resins and have different corrosion resistance.For example, phenolic resin impregnation is acid resistant, but not alkali resistant;Those impregnated with furfuryl alcohol resin are resistant to both acid and alkali.Different varieties of heat resistance is also different: carbon and graphite in reducing atmosphere can withstand 2000~3000℃, in the oxidation atmosphere at 350℃ and 400℃ began oxidation;Impermeable graphite varieties vary with the impregnating agent, usually phenolic or furfuryl alcohol impregnated under 180℃.

5, graphite material 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 accuracy, the surface is bright and clean high yield, without processing or make a little processing can use, thus saving a large amount of metal.Production of cemented carbide and other powder metallurgy processes, usually made of graphite materials for pressing and sintering porcelain boats.Crystal growth crucible, area refining container, bracket fixture, induction heater and so on are all made of high purity graphite.In addition, graphite can also be used for vacuum smelting of graphite heat insulation board and base, high temperature resistance furnace tube, bar, plate, lattice and other components.

6, graphite materials can be used in the atomic energy industry and national defense industry: graphite has a good neutron moderator used in atomic reactors, uranium - graphite reactor is a widely used atomic reactor.As the decelerating material in the power reactor, it should have the characteristics of high melting point, stability and corrosion resistance. Graphite can fully meet the above requirements.Graphite, used in atomic reactors, requires a high purity, with impurities no more than a few dozen PPM.In particular, the boron content should be less than 0.5PPM.Graphite is also used in the defense industry to make solid fuel rocket nozzles, parts for space navigation equipment, heat insulation and radiation protection materials.

7, graphite material graphite can also prevent the boiler scale, the relevant unit test shows that adding a certain amount of graphite powder in water (about 4 to 5 grams per ton of water) can prevent the boiler surface scale.In addition, graphite coating on metal chimneys, roofs, Bridges and pipelines can be used to prevent corrosion and rust.

8, graphite material can be used as pencil lead, pigment, polishing agent.After special processing of graphite, various special materials can be made for relevant industrial departments.

9. Graphite material can be used as the electrode and graphite gradually replaces copper as the material of EDM electrode.

10, graphite looks very black, is the life of the pure quality of graphite in the world and the great role of the balance of the human body, graphite is also commonly known as "black gold" with graphite instead of metal used in eating utensils ink household products, graphite cooking utensils, graphite tea set, graphite mattress graphite crafts.
