Abstract: This study, the thermo-mechanical behavior of barkin-ladi was assessed with a view to investigating its appropriateness for refractory furnace lining. The study involved physical, mechanical and thermal properties which were investigated, evaluated and its suitability for refractory brick used for furnace lining was ascertained. At the best sintering temperature of 1200°C, the following results of the fireclay brick showed the apparent porosity of 24.26%, bulk density of 1.82 g/cm3, firing shrinkage of 9%, cold crushing strength of 16.02 MPa, thermal shock resistance of 24 cycles and a refractoriness of 1665°C. Based on these results the fireclay brick has excellent foundry properties that present it as suitable for the production of fireclay bricks for furnace lining.
