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 materials and as a wear-resistant lubricant.

High Purity and Graphite powder Properties

The graphite-powder chemical properties are stable at room temperatures. They are not soluble in water, dilute acid, dilute alkali, or organic solvents. Under heating graphite powder can be more easily oxidized with acid. It can also react at high temperature 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. 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 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 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 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 solvents.

Graphite is a tough powder that can be shaped into very thin flakes.

Graphite Powder can withstand extreme temperature changes when it is used at room temperatures. Graphite’s volume does not change when the temperature suddenly changes.
