This work is directed at studying the effect of temperature difference on the Thermal Shock Resistance (TSR) of Onibode fireclay material deposit from Ogun State South West Nigeria. TSR is one the very important properties of refractory materials which determines the durability or life span of the material in service. As a result, thermal shock resistance of the materials was studied under different temperatures to determine the behavior of the materials upon addition of alumina in different proportions. Thermal shock resistances of the materials at 900 0C, 1.000 0C, 1,100 0C, 1,200 0C, 1,300 0C and 1,400 0C, respectively of different batches of experimental samples were recorded.The result of the experiment revealed that, with the increase in temperatures, the thermal shock resistance of the material decreases. This has been attributed to the state of the material leaving a very high temperature to very low temperature zones which affects the material structures; as expansion and contraction of the materials at elevated and low temperatures were very high due to the porosity of the materials. Consequently, the shock on the material will be very high leading to the decrease in the cycles recorded.
