ABRASION RESISTANT REFRACTORY COMPOSITION

摘要

A refractory composition characterized by abrasion resistance and low thermal conductivity comprising about 40 to about 96 weight percent amorphous silica, about 2 to about 50 weight percent -65 mesh calcined refractory aggregate having a density of at least about 140 lb/ft3 and about 2 to about 40 weight percent calcium aluminate cement.
