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 chemically sensitive substance. Its resistance will change with different environments. Graphite Powder is a very good non-metallic conductive substance. As long the graphite is not interrupted in the insulating material, it will energize 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.
2) Electrical conductivity and thermal conductivity. The electrical conductivity in graphite is 100 times higher than the conductivity of non-metallic mineral materials. 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 smaller the flakes are, the lower the friction coefficient is and the more lubricating the powder will be.
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 normal room temperature. When temperature suddenly changes, graphite’s volume does not change and there are no cracks.

High Purity and Graphite powder Properties
Graphite powder is easier to oxidize by acid under heating. It is easier for graphite to oxidize by acid when heated. However, at high temperatures it can react with metals and form metal carbides which can melt metals.Graphite Powder is a chemically sensitive substance.
