ABSTRACT:
An improved chromia-magnesia refractory product of co-fused chromia-magnesia grains bonded by an in situ formed chromia bond is prepared by substantially avoiding the presence of grains that will pass through a screen with openings of 150 microns. The resultant product exhibits improved resistance to silicieous materials such as are present in coal slags.
