Graphite powder Graphite powder is a type of mineral, the main constituent is carbon simple substance. It’s soft and dark gray in 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

It is insoluble in organic solvents, water, dilute acid, and dilute alkali. Under heating, graphite can be more easily oxidized by acids. It can also react at high temperatures with many metals, forming metal carbides that can melt metals.

Graphite Powder is a chemically reactive substance. Its resistance will change with different environments. Graphite Powder is a very good non-metallic conductive substance. The graphite will be powered as long as it is not interrupted in the insulating material.

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 low if graphite powder is heated to ultra-high temperatures. 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 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 larger the graphite flakes are, the lower the friction coefficient is and the greater the lubricating properties.

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 sudden temperature changes and not be damaged when it’s used at ambient temperature. Graphite’s volume does not change when the temperature suddenly changes.
