What is high-purity graphite powder? High-purity graphite powder is one of the important raw materials for the production of pencil lead; It is also the raw material for making refractory materials and coatings; It is also an important carbon material, which is widely used in the metallurgical industry as a deoxidizer for steelmaking and manufacturing artificial diamond and refractory materials. In the chemical industry, it is mainly used to purify metals or alloys and as a protective gas in preparing hydrofluoric acid and other strong corrosive substances. In the mechanical industry, it is widely used to produce seals for automotive engine components.
National Defense Application of High-Purity Graphite Powder In the atomic energy and national defense industries, graphite has good neutron retarders used in atomic reactors. Uranium graphite reactor is a kind of atomic reactor that is widely used. Retarding materials used in atomic energy reactors for power should have high melting points, stability, and corrosion resistance. Graphite can fully meet the above requirements. Graphite used in atomic reactors has high purity requirements; the impurity content should not exceed dozens of PPMs, especially the boron content should be less than 0.5 PPMs. In the national defense industry, graphite is also used to make nozzles of solid fuel rockets, nose cones of missiles, parts of aerospace equipment, thermal insulation materials, and radiation shielding materials.
Conductivity Principle of High-Purity Graphite Powder General rubber is insulated. If conductive materials are needed, conductive materials should be added. Graphite powder has superior conductivity and lubrication demolding properties. Graphite powder is processed into graphite powder with excellent lubrication and conductivity. The higher the purity of graphite powder, the better the conductivity. Many special rubber products factories need conductive rubber, so can graphite powder be added to rubber to conduct electricity? The answer is yes, but there is also a question: what is the proportion of graphite powder in rubber? The proportion of some enterprises is no more than 30% on wear-resistant rubber products, such as automobile tires, etc., and the proportion of special rubber plants is 100% so that the conductive body can conduct electricity. The basic principle of conductivity is that the conductive body cannot be interrupted, just like a wire; if it is interrupted, it will not be energized. The conductive graphite powder in the conductive rubber is the conductor. If the graphite powder is separated by insulating rubber, it will not conduct electricity. Therefore, the conductive effect may not be good if the proportion of graphite powder is less.
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 cost of high-purity graphite powder. A large amount of large amount will be lower. The price of high-purity graphite powder can be found on our company's official website.
