Product Description

SUOYI High Purity C Graphite powder lubricating material with factory price
 

Graphite powder is a mineral powder, the main component of which is carbon. It is soft and black-gray. It feels greasy and can contaminate paper. Its hardness is 1-2, and it can increase to 3-5 along the vertical direction with the increase of impurities. Its specific gravity is 1.9-2.3. Under the condition of oxygen isolation, its melting point is above 3000ºC, and it is one of the most temperature-resistant minerals. The chemical properties of graphite powder are relatively stable at room temperature, and it is insoluble in water, dilute acid, dilute alkali and organic solvents. The material has high temperature resistance and electrical conductivity, and can be used as refractory material, conductive material, and wear-resistant lubricating material.
