Mixtures formulated from MgO‐TiN‐NiO were investigated in a search for a high‐temperature refractory material. Components were selected on the basis of their physical and chemical properties. Sintering was performed in a protective argon atmosphere. NiO was reduced or dissociated to nickel metal during the sintering operation. Titanium nitride was introduced to promote a bond between the metallic phase, nickel metal, and the ceramic oxide, MgO. Data is presented for three compositions evaluated for transverse strength, resistance to oxidation expressed as per cent weight gain, and thermal shock in terms of transverse strength. Several compositions exhibited increased transverse strength after being exposed to an oxidizing atmosphere.
