High-purity graphite powder properties<\/h2>\n

High temperature resistance and thermal conductivity<\/strong><\/p>\n

The melting point of graphite is 3850\u00b150\u00b0C, and the boiling point 4250\u00b0C. The thermal expansion coefficient is very small, at 1.4\u00d710^-6\/K. This makes it able to reduce the material loss at high temperatures. Furthermore, the thermal conductivity of high purity graphite powder at room temperature can reach 2.17\u00d710^6 W\/(cm\u00b7K), this value may vary due to the measurement method and unit conversion. But it can still show the generally superior thermal conductivity of graphite powder at room temperature. Due to the high thermal conductivity and high temperature resistance of graphite powder, it can quickly transfer heat and reduce heat accumulation. While it can stay stable at high temperatures.<\/p>\n

Electrical:<\/strong> due to its special crystal structure, graphite has good electrical conductivity. The higher the purity of graphite, the smaller the particle size, the stronger the conductivity. Thus our high purity graphite powder is able to provide excellent electrical conductivity.<\/p>\n

Lubricity:<\/strong> High purity graphite powder contain fewer impurities, providing better lubrication and reducing friction and wear. High purity graphite particles are more likely to form a uniform lubricating film, thus reducing the contact between mechanical surfaces. The larger the flake, the smaller the friction coefficient, the better the lubrication performance.<\/p>\n

Chemical stability:<\/strong> \u0627\u0644\u062c\u0631\u0627\u0641\u064a\u062a<\/a> has good chemical stability at room temperature.\u00a0And it can resist acid, alkali and organic solvent corrosion.<\/p>\n

 <\/p>\n

Applications of\u00a0High purity graphite powder<\/h2>\n

Lubricant:<\/strong> Due to its low friction coefficient and sheet structure, graphite powder is often used as a dry lubricant, especially in high temperature or high vacuum environments. People use it widely in the lubrication of mechanical parts, such as bearings and gears.<\/p>\n

\u0635\u0646\u0627\u0639\u0629 \u0627\u0644\u0645\u0639\u0627\u062f\u0646:<\/strong> Graphite powder<\/a> is also a common reducing agent in metallurgical industry. It helps remove impurities in metals and improve the purity, hardness and strength of metals. In addition, it is also an alloy additive for \u0635\u0646\u0627\u0639\u0629 \u0627\u0644\u0635\u0644\u0628<\/a> and non-ferrous metals.<\/p>\n

Fireproof materials:<\/strong> Some types of graphite powder can be added to fireproof materials to improve their fire resistance.<\/p>\n

Casting and mold release agent:<\/strong> During the \u0627\u0644\u0635\u0628<\/a> process, graphite powder acts as an isolating layer. It prevents the metal from sticking to the mold and ensure smooth release. In mold manufacturing, it also acts as common release agent.<\/p>\n

Corrosion resistant and sealing material:<\/strong> Graphite powder is also common in sealing materials. Such as gran powder (sealing anti-stick grease). People widely use it in ships, aircraft, locomotive and other large machinery metal bonding surface, flange connection parts of the seal and anti-stick. The excellent corrosion resistance enables graphite to maintain efficient sealing performance in harsh environments for a long time. So they are also common in the chemical and petroleum industries.<\/p>\n

Light industry:<\/strong> Graphite powder is a polishing agent and anti-rust agent for glass and paper making in light industry. It is also an indispensable raw material for the manufacture of pencils, ink, black paint, ink and synthetic diamonds etc.<\/p>\n

\u0627\u0644\u0635\u0646\u0627\u0639\u0629 \u0627\u0644\u0643\u064a\u0645\u064a\u0627\u0626\u064a\u0629:<\/strong> People use graphite powder to make chemical equipment such as heat exchangers and reaction tanks. It can also acts as release lubricants for the production of catalysts in the fertilizer industry.<\/p>\n

 <\/p>\n

Furthermore, graphite powder can also be used as pigment and coating materials, lubricants in cable production, and for the production of carbon film resistance, conductive dry die. In general, the use of graphite powder is very wide, covering almost every area of industrial production.<\/p>","protected":false},"excerpt":{"rendered":"

High-purity graphite powder is graphite powder with a purity (carbon content) of more than 99.9%.\u00a0Under the condition of isolation of oxygen, the melting point of graphite powder is above 3000 \u00b0 C, which makes it one of the most temperature-resistant minerals.\u00a0What\u2019s more, graphite powder has relatively stable chemical properties under room temperature.<\/p>\n

High-purity graphite powder can be used as lubricants, electrodes, refractory materials and composite
