Today we will briefly introduce the effect of impurities on graphite oxidation at high temperature.

All kinds of trace metal impurities can promote the high temperature oxidation of graphite. For example, Fe, Co, Ni, Ca, Mn, Mo, V, Au, Pt, Ag, AI, Ga, Ge, Sn, Pb, As, Sb, Bi, Se, Te, Ta, Ti, B, alkali metal, alkaline-earth metals, etc.

Because graphite contains such impurities and the distribution of these impurities is uneven, the repeatability of the reaction rate data of graphite oxidation at high temperature is poor.
