Calcium aluminate clinker as a refractory aggregate with and without barium addition and use thereof

摘要

The present invention provides for a refractory aggregate composition comprising an improved calcium aluminate clinker having the formula C_nA_x wherein C is calcium oxide and A is aluminum oxide, wherein n is an integer from about 1 to about 12, wherein x is an integer from about 1 to about 24, and wherein said clinker has less less than about fifty weight percent C₁₂A₇. Analogs, derivatives and hydrates of the improved calcium aluminate clinker are provided. A refractory composition and a sprayable refractory composition are disclosed comprising the improved calcium aluminate clinker.
