A refractory material composed of conventional fused or tabular alumina grains, bonded by a novel bonding phase that shows X ray diffraction lines characteristic of both sialon and silicon oxynitride, with the latter predominating, has a modulus of rupture at 1450 C of more than 350 bars and good thermal shock resistance. The material can be made by mixing appropriate amounts of silicon metal powder, fine reactive alumina, and a fine silica source such as bentonite clay with the alumina grains and a binder and dispersant liquid to form a refractory mass suitable for shaping, then shaping, and heating the shaped body in a nitrogen atmosphere.
