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/cm 3 bulk density and porosity of 20.4%. A cold crushing strength of 17.48 MN/m 2 was obtained with modulus of rupture of 8.28 MN/m 2 . The thermal shock resistance exceeded 30 cycles and the refractoriness was 1750˚C. The sample was analysed for its chemical composition, and it was revealed that it contained 38.07% alumina (Al 2 O 3 ), 46.00% silica (SiO 2 ) and iron impurities (Fe 2 O 3 ) of 0.78%. The results generally showed that Ozanagogo clay could be used as a refractory material.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
