Why graphite powder is so heat-resistant?


What's graphite powder, exactly?
The hardness and vulnerability of

graphite powder

It is 12. The vertical direction can see a rise in hardness to 35 for increased impurities. It has a specific gravity of 1.92.3. Under the condition of oxygen isolation, its melting point is above 3000 , one of the most temperature-resistant minerals. The chemical properties of graphite are very stable when it is room temperature. It is insoluble with water, dilute acid and alkali as well as an organic solvent. It has high-temperature resistance, conductivity, and can also be used to lubricate surfaces that are conductive, wear-resistant, or refractory. Graphite is a material with a highly sensitive chemical reaction. Its resistance will fluctuate in different environments. However, the value of its resistance will never change. Graphite powder can be used as a non-metallic conductive material. As long the graphite is kept in an insulating item, the powder will be energized as if it were a wire. There is no exact resistance value as graphite is thicker than graphite so it is difficult to determine the right number. The resistance will also vary for different environments and materials.


Use of graphite dust


Graphite exhibits good chemical stability. Graphite can also be processed to have good corrosion resistance, thermal conductivity and low permeability. This graphite is used extensively in the manufacture of heat exchangers. It can be found in many industries, including the petrochemical and hydrometallurgy industries, as well as paper and synthetic fiber production. Because graphite has a low thermal expansion coefficient, and it is able to withstand extreme temperatures and cooling changes, you can use it as a mold to make glassware. With graphite as a casting material, ferrous metal is possible with exact dimensions and high yields of smooth surfaces. It can also be cast without any processing. Graphite can be used for ceramic boats, die casting, and sintering of cemented carbide or other powder metallurgy process. All of the high-purity graphite components, such as the regional refining container and m bracket fixture and induction heater are made from graphite.


Conductive principle in graphite powder


Isolated general rubber can be used. Conductive materials can be used if they are required. Graphite is a graphite powder with superior conductivity, lubrication demolding and lubrication properties. Graphite dust is converted into graphite, which has high conductivity and lubrication. Higher grades of graphite powder will have better conductivity. There are many special rubber product factories that require conductive rubber. So graphite powder could be added to rubber in order to conduct electricity. Although the answer is yes, there's also a question. What is the ratio of graphite to rubber? For wear-resistant rubber products such as automotive tires, the percentage used by certain companies is less than 30%. The special rubber plant's proportion is 100 percent so conductivity is possible. Conductivity's basic principle is that the conductive body is indestructible. It cannot be broken, and it can be disconnected. Conductors are the conductive graphite and conductive rubber. Conductivity is lost if graphite dust is separated with insulating rubber. If the graphite content is lower, it may result in a less conductive effect.


Price of graphite dust


The product's price will depend on its particle size, purity and purchase volume. Large quantities of high quality graphite will result in a lower price. Our company's website contains the graphite price.
