Graphite raw material high purity flake graphite
The use of high purity graphite in the field of industrial production has excellent performance. High purity graphite is used in conductive, lubrication, metallurgy, and other industrial production fields. High purity graphite production, from the beginning of the raw materials, should be strictly controlled the content of impurities, choose low ash raw materials, and in the production process to prevent the increase of pollutants as far as possible. However, the reduction of contaminants to the degree required is primarily in the graphite chemical sequence. Graphitization occurs at high temperatures, where the oxides of many impurity elements will decompose and evaporate. The higher the graphitization temperature is, the more impurities are discharged, the higher the purity of the high purity graphite products are produced. The high purity graphite is used to make use of its excellent conductivity, lubrication, high-temperature resistance, etc.

High purity graphite is a high purity, fewer impurities. This depends on the complete production process and production equipment.
Special properties of graphite
1. Chemical stability: Graphite in the room temperature has excellent chemical durability, acid resistance, alkali resistance, and resistance to organic solvent corrosion.
2. Plasticity: Graphite toughness is good, can be ground into a fragile sheet.
3. Thermal shock resistance: Graphite in the room temperature when used to withstand the dramatic changes in temperature without destruction, temperature mutation, the volume of graphite changes little, will not produce cracks
Application field
(1) Isotropic nuclear graphite industry
Because high purity isotropic natural microcrystalline ink is an ideal raw material for atomic graphite, it is particularly important to expand the source of raw materials for high purity isotropic natural microcrystalline ink.
(2) Artificial diamond industry
Natural flake graphite powder is the primary raw material of synthetic diamond. Scientists have proved that the purity of graphite powder and the graphitization degree of graphite powder have a significant influence on product quality. The selection of high purity graphite raw materials and the selection of appropriate graphitization degree will be an essential way to improve the product quality of an artificial diamond.
