are provided for a study of the effect of different graphites GÉ-1 and GCh (Russian Federation), Falke 94100 and Falke 9280 (Brazil), +592 (PRC), +595 (Madagascar), and FLS 897 (Norway) on physicochemical properties of periclase- and corundum-graphite refractories. It is shown that the type of graphite affects charge properties even in the preparation stage, and object physicochemical properties.
