Are you familiar with Graphite? Graphite is an allotrope of carbon. It is a gray-black, opaque solid with stable chemical properties and corrosion resistance. It is not easy to react with chemicals such as acids and alkalis. Natural graphite comes from graphite deposits, and it can also be made into artificial graphite by using petroleum coke, pitch coke, etc., as raw materials through a series of processes. Graphite burns in oxygen to generate carbon dioxide, which can be oxidized by strong oxidants such as concentrated nitric acid and potassium permanganate. It can be used as an anti-wear agent and lubricant; high-purity graphite is used as a neutron moderator in atomic reactors and can also be used to manufacture crucibles, electrodes, brushes, dry batteries, graphite fibers, heat exchangers, coolers, electric arc furnaces, Arc lamps, pencil refills, etc.
The Physical and chemical properties of Graphite Graphite is soft, black-gray, greasy and can contaminate paper. The hardness is 1-2, and its hardness can increase to 3-5 along with the increase of impurities along the vertical direction. The specific gravity is 1.9-2.3. The specific surface area is concentrated in the range of 1-20m2/g, and its melting point is above 3000°C under the condition of cutting off oxygen. It is one of the most temperature-resistant minerals. It conducts electricity and heat. There is no pure graphite in nature, and it often contains SiO2, Al2O3, FeO, CaO, P2O5, CuO, and other impurities. These impurities often appear in the form of minerals such as quartz, pyrite, and carbonate. In addition, there are gas parts such as water, asphalt, CO2, H2, CH4, N2, etc. Therefore, in the analysis of graphite, in addition to determining the fixed carbon content, the content of volatile matter and ash must also be determined at the same time. Graphite, diamond, carbon 60, carbon nanotubes, graphene, etc., are all simple substances of carbon, and they are allotropes of each other.
The Advantage of Graphite Powder
1. High-temperature resistance The melting point of graphite is 3850±50°C. Even if it is burned by an ultra-high temperature arc, the weight loss is very small, and the thermal expansion coefficient is also very small. The strength of graphite increases with the increase in temperature, and at 2000°C, the strength of graphite doubles. 2. Chemical stability Graphite has good chemical stability at room temperature, and is resistant to acid, alkali and organic solvents 3. plasticity Graphite has good toughness and can be ground into very thin flakes. 4. Electrically conductive and thermally conductive The conductivity of graphite is one hundred times higher than that of common non-metallic minerals. Thermal conductivity exceeds that of metal materials such as steel, iron, and lead. Thermal conductivity decreases with increasing temperature, and even at extremely high temperatures, graphite acts as a thermal insulator. Graphite can conduct electricity because each carbon atom in graphite forms only 3 covalent bonds with other carbon atoms, and each carbon atom still retains 1 free electron to transport charges.
Applications of Graphite Graphite can be used to produce refractory materials, conductive materials, wear-resistant materials, lubricants, high-temperature resistant sealing materials, corrosion-resistant materials, heat insulation materials, adsorption materials, friction materials and radiation protection materials, etc. These materials are widely used in metallurgy, petrochemical industry , machinery industry, electronics industry, nuclear industry and national defense, etc.
