Graphite powder
It’s a type of mineral powder. The main component is carbon-simple substance. It has a dark grey 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 sensitive substance. Its resistance will change with different environments. Graphite Powder is one of very good 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) Type high temperature resistant: The melting and boiling points of graphite are 3850+-50°C, respectively. Weight loss and thermal expansion coefficient will be very small even if graphite is burnt by an ultra-high temperature arc. 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 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 properties of graphite powder are 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 made into thin flakes.
Graphite Powder can withstand extreme temperature changes when it is used at room temperatures. The volume of graphite does not change when the temperature suddenly changes.

High Purity and Graphite powder Properties
Graphite powder is easier to oxidize by acid under heating. The graphite is more easily oxidized when heated. It can also be used to smelt many metals by forming metal carbides.Graphite Powder is a sensitive substance. Its resistance will change with different environments.
