ABSTRACT
Abstract: Mubi clay was investigated to examine if the deposit can be used as a furnace lining material. The result shows that the clay has a bulk density of 2.3g/cm3, apparent porosity of 13.70%, firing shrinkage of 9.6%, thermal shock resistance of 8 cycles, cold crushing strength of 253 kg/cm2, loss on ignition of 4% and refractoriness of 1,300 0C. The percentage composition of impurities is generally below 2.0% while iron II oxide account for 5.986%. The chemical analysis shows that the percentage composition of Aluminium oxide (Al2O3) is 18.1% while the Silica (SiO2) content is 67.7%. The results obtained from Mubi clay showed that the clay can be used for lining of heat treatment furnace, melting furnaces for low melting point metals, liquid metal ladles and portions of blast furnaces.
