What is high-purity graphite powder? High-purity graphite powder it is also made of high-purity graphite powder with high carbon content after a step by step crushing and purification. The carbon content of high-purity graphite powder is generally 99.9% or more, which makes high-purity graphite powder have very good use in the field of high-temperature resistance and electrical conductivity. High-purity graphite powder has the advantages of high strength, oxidation resistance, small resistance coefficient, good thermal shock resistance, corrosion resistance, easy precision machining, high-temperature resistance, etc.; it is an important raw material in industrial production.
Use of high-purity graphite powder Graphite has good chemical stability, corrosion resistance and thermal conductivity, and is widely used in petrochemical, hydrometallurgy, acid and alkali production, synthetic fiber, paper and other industrial sectors. It is used to make heat exchangers, reaction tanks, condensers, combustion towers, absorption towers, coolers, heaters, filters, pumps and other equipment. Graphite has good neutron deceleration performance, and is used as a retarder in atomic reactors. Uranium-graphite reactor is a kind of atomic reactor that is widely used at present. In the national defense industry, graphite can be used to manufacture nozzle of solid fuel rocket, nose cone of missile, parts of space navigation equipment, thermal insulation material and anti-radiation material.
Preparation of high-purity graphite powder The graphite powder raw material is added to the graphite boat, the graphite boat is installed in the graphite purification equipment, and argon is introduced for purging; Inject purified gas A at the temperature of 1200-1800 ℃ and keep it for 0.5-2h; When the temperature rises to 2000-2400 ℃, inject purified gas B and continue to inject purified gas A; When the temperature rises to 2600-3000 ℃, stop the introduction of purified gas A and purified gas B, hold for 0.5-2h, and cool to room temperature to obtain high-purity graphite powder; Among them, argon needs to be continuously injected for protection during the whole preparation process. The invention combines the science of gas-thermal purification and high-temperature purification to remove the key impurities such as B, Al and V from the raw material of graphite powder, so as to obtain high-purity graphite powder with purity ≥ 99.9999%, which creates conditions for the industrial production of high-purity graphite powder with carbon content above 99.9999% and provides a certain scientific basis.
Price of high-purity graphite powder High-purity graphite powder particle size and purity will affect the product's price, and the purchase volume can also affect the high-purity graphite powder cost. A large amount of large amount will be lower. The high-purity graphite powder price can be found on our company's official website.
