ABSTRACT:
A basic fused refractory material consisting essentially of, by weight on the oxide basis, 50-67% MgO, 33-50% CaO, and preferably at least 98% MgO + CaO. The method of producing the fused refractory material by melting and solidifying a batch of refractory raw materials, wherein the cooling rate inducing solidification throughout the fused melt is at least 600 Centigrade degrees per hour and sufficient to yield the fused refractory product characterized by a fine microstructure retaining at least 2.0% MgO in solid solution in the lime phase and increased hydration resistance of the fused refractory material.
