Bauxites from the different profiles in Western India have been studied for the first time with a view to examining their potential as a refractory material. The results show that the sintering behaviour of these Gibbsite-Boehmite-Halloysite (GBH) assemblages proceeded in two stages with (i) a decomposition stage at 400°-l200°C and (ii) mullite formation stage at 1200°-l600°C. Microstructures of the raw !Daterials and sintered pellets were studied to evaluate the possibility of utilizing them in the ceramic industry.
