Interaction of periclase and corundum refractories with iron and iron-manganese melts

The authors have experimentally investigated the reaction of periclase and corundum refractories with iron and iron-manganese melts. They propose a physicochemical scheme of the reaction, taking account of the characteristics of the composition and structure of the specimens. They show the influence of manganese and of the composition of the primary oxide phase on the character of the reaction. The coefficients of diffusion of the primary oxide phase in periclase grains have been determined.
