  ABSTRACT: In this paper, the refractory properties of clay from Ozanagogo had been studied for possible utilization in refractory production. The clay had a specific gravity of 2.57, linear firing shrinkage of 1.01%, 2.14 g/cm3 bulk density and porosity of 20.4%. A cold crushing strength of 17.48 MN/m2 was obtained with modulus of rupture of 8.28 MN/m2. The thermal shock resistance exceeded 30 cycles and the refractoriness was 1750℃. The sample was analysed for its chemical composition, and it was revealed that it contained 38.07% alumina (Al2O3), 46.00% silica (SiO2) and iron impurities (Fe2O3) of 0.78%. The results generally showed that Ozanagogo clay could be used as a refractory material.
