Refractory materials are crucial in industries operating at high temperatures, such as metallurgy, ceramics, and glass manufacturing. This study evaluates the refractory properties of Badeggi clay from Niger State, Nigeria, when mixed with varying proportions of graphite and asbestos additives. Badeggi clay, primarily composed of silica and alumina, has demonstrated potential as a refractory material. Enhancing its properties through additives intends to improve its thermal stability, mechanical strength, and resistance to corrosive agents. In this investigation, Badeggi clay samples were mixed with graphite and asbestos at 20%, 30%, and 40% ratios. The effects on refractoriness, thermal shock resistance, apparent porosity, bulk density, specific gravity, and firing shrinkage were systematically studied. Results indicated that the initial refractoriness of Badeggi clay, at 1400ºC, increased to 1700ºC with graphite and 1600ºC with asbestos additives. Firing shrinkage remained consistent across samples at 3.5%. Thermal shock resistance decreased with higher additive content, while apparent porosity and bulk density increased. Specifically, graphite and asbestos enhanced the refractory properties, with the optimal compositions found at 30% graphite and 40% asbestos for improved insulation and durability. The study concludes that Badeggi clay, with appropriate additive ratios, is suitable for high-temperature applications such as furnace linings and general-purpose bricks. Future research should explore additional additives like sawdust and rice husk to further enhance the clay's properties. These findings contribute to materials science, offering insights into optimizing local resources for industrial use.
