Why graphite powder materials have high temperature resistance and conductivity?
What is graphite powder?
Graphite powder is a kind of mineral powder, mainly composed of carbon, soft and dark gray; it is greasy and can pollute the paper. The hardness is 1~2. The hardness can increase to 3~5 with increased impurities in the vertical direction. The specific gravity is 1.9~2.3. Under the condition of isolating oxygen, its melting point is above 3000 ℃, and it is one of the most temperature-resistant minerals. At normal temperatures, the chemical property of graphite powder is relatively stable and insoluble in water, dilute acid, alkali, and an organic solvent; the material has high-temperature resistance and conductivity and can be used as a refractory, conductive material, wear-resistant and lubricating material. It reacts with oxygen at different temperatures to generate carbon dioxide or carbon monoxide; in halogen, only fluorine can react directly with carbon; Under heating, graphite powder is easily oxidized by acid; At high temperatures, it can react with many metals to form metal carbides, and can smelt metals at high temperature.
Classification of graphite powder
Gland powder (sealing and anti-sticking grease) performance and use: high-temperature resistance of 3000 ℃, high-pressure resistance of 40KG, used for sealing and anti-sticking of metal joint surfaces, and flange joint parts of ships, aircraft, locomotives, automobiles, construction machinery and various large petroleum, chemical and electrical machinery
Special graphite coating: water-based graphite coating, conductive graphite coating, dissolved graphite coating, internal and external graphite coating, brushed graphite coating, lubricating graphite coating, glass fiber coating, television graphite coating, and special coating, various non-metallic materials, nanometer material production process, design scheme. Handle various anti-corrosion equipment, and undertake various anti-corrosion equipment treatments.
Thermal conductivity theory of graphite powder
The theory of thermal conductivity of graphite crystal is very complicated, and much progress has been made with the help of computers. However, there are still many problems to be further discussed λ A. For example, quantize the lattice vibration wave and vividly call the vibration wave phonon. The vibration wave is a vector, which can be called a wave vector. The energy and state of the wave vector are functions of the reciprocal crystal lattice. A small region can represent the entire crystal reciprocal lattice, called the Brillouin area. As long as the energy and state of phonons in this area are clear, the situation of phonons in the whole crystal will be clear.
Price of graphite
Graphite particle size and purity will affect the product's price, and the purchase volume can also affect the cost of graphite. A large amount of large amount will be lower. The price of graphite can be found on our company's official website.
