Main ingredients of graphite powder?
There are water, asphalt, CO2, H2, CH4, N2 and other gas parts. Therefore, the determination of graphite, in addition to the determination of fixed carbon content, but also the simultaneous determination of volatile and ash content.
These impurities often appear in quartz, pyrite, carbonate and other minerals.
In nature there is no pure graphite, which often contains SiO2, Al2O3, FeO, CaO, P2O5, CuO and other impurities.
