THE THERMODYNAMIC BASIS FOR USING ALUMINUM-MAGNESIUM SPINEL IN LOW-CEMENT REFRACTORY CONCRETES

摘要

The paper discusses the use of aluminum-magnesium spinel (previously synthesized or formed during use) in refractory concretes not only from the viewpoint of its high stability and scope for the formation of solid solutions with components of steel-melting slag and also of good thermophysical properties but also from the purposive reactive formation of structures with elevated high-temperature strength.
