Graphite powder
The main component of this mineral powder is carbon, which is soft and dark gray in color. Graphite is a powder with high temperature resistance, electrical conductivity. It’s used in refractory material, conductive material, and wear resistant lubricating materials.
Graphite Powder is a chemically reactive substance. Its resistance will change with different environments. Graphite Powder is one of the best non-metallic conductive substances. As long the graphite is not interrupted in the insulating material, it will be powered like a thin cable.
The special properties of graphite are due to the special structure of its powder:
1) High-temperature resistant type: The melting and boiling points of graphite are 3850+-50°C, respectively. Weight loss is minimal even when burned with an ultra-high temperature arc. Thermal expansion coefficients are also small. With increasing temperature, the strength of powdered graphite increases. The strength of the graphite doubles at 2000degC.
2) Electrical and Thermal Conductivity: Graphite’s electrical conductivity is 100 times greater than the conductivity of non-metallic minerals in general. The thermal conductivity of graphite is greater than metal materials like steel, iron and lead. The thermal conductivity drops with temperature. Even at very high temperatures, graphite is an insulator.
3) Lubricity: The lubricating properties of graphite powder depend on the size graphite flakes. The larger the graphite flakes are, the lower the friction coefficient is and the greater the lubricating properties.
4) Chemical stability Graphite is chemically stable at room temperatures and resistant to acids, alkalis, and organic solvent corrosion.
5) Plasticity Graphite is a tough powder that can be shaped into thin flakes.
6) Thermal Shock Resistance: Graphite Powder can withstand dramatic changes in temperature when used at room temperatures. The volume of graphite does not change when the temperature suddenly changes.

High Purity and Graphite powder Properties
The graphite is a powder that can be oxidized more easily by acids when heated. The graphite powder becomes more oxidized when heated. It can also be used to smelt metals by forming metal carbides at high temperatures.Graphite Powder is a chemically reactive substance. Its resistance will change with different environments.
