Production
Flake graphite is a natural crystalline graphite, which is similar to fish phosphorus and belongs to hexagonal crystal system. It has layered structure. It has good properties of high temperature resistance, conductivity, heat conduction, lubrication, plasticity and acid-base resistance.
Flake graphite is a natural lubricant with a layered structure, rich in resources and cheap in price.

Natural graphite is formed by the transformation of carbon-rich organic matter under the long-term action of high temperature and high pressure geological environment, and is the crystallization of nature. The technological characteristics of natural graphite mainly depend on its crystalline form. Minerals with different crystalline forms have different industrial values and uses. There are many kinds of natural graphite. According to the different crystalline morphology, natural graphite is divided into dense crystalline graphite, flake graphite and cryptocrystalline graphite.
Application:
1. As refractories
2. As conductive material
3. As wear-resistant lubricating material
4. Graphite has good chemical stability. After special processing, graphite has the characteristics of corrosion resistance, good thermal conductivity and low permeability, so it is widely used to make heat exchanger, reaction tank, condenser, combustion tower, absorption tower, cooler, heater, filter and pump equipment. Widely used in petrochemical, hydrometallurgy, acid and alkali production, synthetic fiber, paper and other industrial sectors, can save a lot of metal materials.
5. For casting, sanding, die-casting and high-temperature metallurgical materials
6. For the atomic energy industry and national defense industry
7. Graphite can also prevent the boiler from scaling.
8. Graphite can be used as pencil lead, pigment and polishing agent. After special processing, graphite can be used to make all kinds of special materials for relevant industrial departments.
