HP Graphite Powder

Graphite powder is soft, dark gray; it has a greasy feel and can stain paper. The hardness is 1~2, and the hardness can increase to 3~5 with the increase of impurities in the vertical direction. The specific gravity is 1.9~2.3. Under the condition of isolating oxygen, its melting point is above 3000℃, which is one of the most temperature-resistant minerals.

Graphite powder Classification  for sale can be divided into regular power graphite powder (RP),high power graphite powder(HP) and ultra high power graphite powder based on its quality index
