Conclusions
Of the experimental carbon-containing materials as candidates for use in the refractory composite MgO-C of periclase products, the optimum is natural crystalline graphite from the Zaval'evsk Deposits. The nature and structural features of the carbon are the most important indicative characteristics.
Of the experimental forms of binder, the best antioxidant of carbon is sodium polyphosphate. The interaction between P2O5 and catalytic impurities of the graphite led to their deactivation and to a lowering of the rate of carbon oxidation.
