Graphite powder
This mineral powder is soft, dark gray, and has a carbon-simple substance as the main constituent. Graphite is a powder with high temperature resistance, electrical conductivity. It’s used in refractory material, conductive materials and as lubricants.
Graphite Powder is a chemically reactive substance. Its resistance will change with different environments. Graphite Powder is a good non-metallic conductive substance. Graphite powder, as long as it is not interrupted in the insulating material, will be energized just like a thin metal wire.
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. At 2000degC the strength of graphite powder doubles.
2) Electrical and Thermal Conductivity: The electrical conductivity graphite is 100 times greater than other non-metallic minerals. 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 lubricating effect 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 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. When temperature suddenly changes, graphite’s volume does not change and there are no cracks.

High Purity and Graphite powder Properties
The chemical properties are stable at room temperatures, and graphite powder is insoluble in dilute acids, alkalis, organic solvents, or water. When heated, graphite can be more easily oxidized with acid. It can also react at high temperature with metals to produce metal carbides which can melt metals.Graphite Powder is a chemically reactive substance.
