Summary

A new ceramic oxide-based, fused-cast refractory has been developed which has an improved corrosion resistance to E-type textile fiberglass. The new material has a primary phase of Cr2O3 and Al2O3 with a minor MgO spinel phase. The high percentage of the of the R2O3 phase is responsible for the improvement in corrosion resistance when compared to other fused-cast products which have similar Cr2O3 contents, but haw higher concentrations of a spinel phase. Experimental results are presented depicting corrosion rates and mechanism for chrome refractries in contact with E-type fiberglass.
