Graphite is widely used in advanced refractory and coatings for the gold industry.Such as magnesium carbon brick, crucible, etc.Stabilizers for pyrotechnic materials in military industry, desulfurization accelerating agents for smelting industry, pencil cores for light industry, carbon brushes for electrical industry, electrodes for battery industry, catalysts for fertilizer industry, etc.After deep processing, flake graphite can produce graphite milk, used for lubricant, mold release agent, wire drawing agent, conductive coating, etc.Also can produce expanded graphite, used for flexible graphite products raw materials, such as flexible graphite seals and flexible graphite composite material products.The main reason why graphite powder is so widely used is that it has the following five advantages:

1. Good thermal conductivity and electrical conductivity

Graphite powder electrical conductivity is good, although not compared with aluminum, iron, copper and other metals, but compared with other ordinary materials, its conductivity is quite high, is carbon steel 3 times, stainless steel 5 times, than other non-metallic materials 100 times higher.Graphite powder has insulation property at ultra-high temperature, which is different from common metal materials. The thermal conductivity of common metal increases with the increase of temperature.Graphite powder tends to be adiabatic at very high temperatures.

2. Super high temperature resistance

Graphite powder is one of the materials which can withstand high temperature.General materials above 2000℃, generally will be molten state or into gas, and graphite powder is not melting, its melting point is about 3900℃, boiling point is 4250℃, and, graphite powder in ultra-high temperature loss rate is very low.In addition, the strength of general materials decreases gradually at high temperature, while the strength of graphite increases twice as much when heated to 2000℃ as when heated to room temperature.

3. Good lubricity

The friction coefficient of graphite powder is less than 0.1, and the lubrication property changes with the scale size, the larger the scale, the smaller the friction coefficient, the better the lubrication property.Graphite powder used in the lubrication industry has the advantage over molybdenum disulfide in that it does not produce a pungent smell at high temperatures.

4. Excellent thermal shock resistance

Graphite powder has good thermal shock resistance, that is, when the temperature suddenly changes, its thermal expansion coefficient is small, so it has good thermal stability, graphite related products will not crack.

5. Good chemical stability

At room temperature, graphite has good chemical stability, can resist the corrosion of acid, alkali and organic solvents.
