Castable and gunning composition with improved resistance to bui ld-up and alkali infiltration

摘要

Mixes suitable for casting or gunning containing a heat-resistant aggregate blend containing at least about 50 wt. % high alumina grain, silicon carbide, and zircon sand, and to the method of utilizing the same to form alkali-resistant linings in high temperature vessels that have improved resistance to build-up./!
