Graphite powder
Graphite powder is a type of mineral, the main constituent is carbon simple substance. It’s 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 sensitive substance. Graphite’s resistance will change with different environments. Graphite Powder is one of the best non-metallic conductive substances. As long as there is no interruption in the graphite, the powder will be powered like a thin metal wire.
The special properties of graphite are due to the special structure of its powder:
1) High-temperature resistant type: Graphite’s melting point is 3850+-50 and its boiling is 4250. 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. At 2000degC the strength of graphite powder doubles.
The thermal conductivity is higher than the electrical conductivity. The thermal conductivity of graphite is greater than metals 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 lubrication performance of graphite powder is improved by larger flakes.
4) Chemical stability Graphite is chemically stable at room temperatures and resistant to acids, alkalis, and organic solvents.
5) Plasticity Graphite is a tough powder that can be connected to very thin flakes.
6) Thermal shock resistance – Graphite Powder can withstand sudden temperature changes and not be damaged if used at ambient temperature. When temperature suddenly changes, graphite’s volume does not change and there are no cracks.

High Purity and Graphite powder Properties
Graphite is more easily oxidized when heated. Under heating, graphite can be more easily oxidized by acids. It can also react at high temperatures with many metals, forming metal carbides that can melt metals.Graphite Powder is a chemically sensitive substance.
