(Ki sa ki se poud grafit)

Graphite powder is soft and dark gray; it has a greasy feel and can stain paper. Dite a se 1-2, and the hardness can increase to 3-5 with the increase of impurities in the vertical direction. Gravite espesifik la se 1.9 pou 2.3. Under the condition of isolating oxygen, its melting point is above 3000℃, which is one of the most temperature-resistant minerals. The chemical properties of graphite powder are relatively stable at room temperature, and are insoluble in water, dilye asid, dilute alkali and organic solvents; the material has high temperature resistance and conductivity, and can be used as refractory materials, materyèl konduktif, and wear-resistant lubricating materials.

It reacts with oxygen at different high temperatures to produce carbon dioxide or carbon monoxide; among halogens, only fluorine can directly react with elemental carbon; graphite powder is easier to be oxidized by acid under heating; at high temperatures, it can also react with many metals to form metal carbonization It can smelt metals at high temperatures.
