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