Special properties of graphite
1. High temperature resistant type: the melting point of graphite is 3850 ± 50 ℃, and the boiling point is 4250 ℃. The strength of graphite increases with the increase of temperature. At 2000 ℃, the strength of graphite is doubled.
2. Conductivity and thermal conductivity: the conductivity of graphite is 100 times higher than that of general non-metallic minerals. Its thermal conductivity exceeds that of metal materials such as steel, iron and lead. The thermal conductivity decreases with the increase of temperature, and even at extremely high temperatures, graphite becomes an insulator.
3. Lubricity: the lubricity of graphite depends on the size of graphite scales. The larger the scales, the smaller the friction coefficient, and the better the lubricity.
4. Chemical stability: graphite has good chemical stability at normal temperature, and can resist acid, alkali and organic solvent corrosion.
5. Plasticity: graphite has good toughness and can be rolled into very thin flakes.
6. Thermal shock resistance: when graphite is used at normal temperature, it can withstand drastic changes in temperature without damage. When the temperature changes abruptly, the volume of graphite changes little and cracks will not occur.
Graphite is widely used as advanced refractory materials and coatings in the metallurgy industry. Such as magnesia carbon bricks and crucibles. Stabilizers for initiating explosive materials in the military industry, desulfurizing accelerators in the refining industry, pencil leads in the light industry, carbon brushes in the electrical industry, electrodes in the battery industry, catalysts in the fertilizer industry, etc. After in-depth processing, flake graphite can produce graphite emulsion, which is used for lubricants, release agents, wire drawing agents, conductive coatings, etc.
There are 150 meshes / 8000 meshes / 15000 meshes / etc
