Thoria compacts containing refractory metal fibers in quantities as low as five per cent have considerably better resistance to thermal shock spalling than thoria alone. Of the metals and alloys investigated, molybdenum and niobium gave the best results. Compacts incorporating fibers of these metals have lower elastic moduli and compressive strengths and higher thermal conductivity than thoria. Oxidation resistance of molybdenum fiber-reinforced thoria is the best of all combinations investigated, but, owing to the presence of microcracks, it is severely attacked after prolonged exposure to an oxidizing atmosphere at 1000 deg C.
