Graphite powder It’s a type of mineral powder. The main component is carbon-based 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.

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. Under heating graphite powder can be more easily oxidized with acid. It can also react at high temperatures with metals to produce metal carbides which can smelt the metals.

Graphite Powder is a chemically sensitive substance. Its resistance will change with different environments. Graphite Powder is one of very good non-metallic conductive substances. Graphite powder, as long as it is not interrupted in the insulating material, will be energized just 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 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.

Graphite has a high electrical and thermal conductivity. The thermal conductivity of graphite is greater than metals like steel, iron and lead. The thermal conductivity drops with temperature. Graphite is an insulator even at high temperatures.

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 lubrication performance.

4) Chemical stability Graphite is chemically stable at room temperatures and resistant to acids, alkalis, and organic solvents.

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. Graphite’s volume does not change when the temperature suddenly changes.
