The effect of nano boehmite on the formation of spinel at low temperatures (T<1000oC) in the alumina-magnesia system via a solid-state route is investigated. The homogeneity of prepared mixtures was studied carefully by X-ray diffraction, FTIR1 and SEM/EDX. This clarified that the formation of spinel was encouraged in the presence of nano boehmite. It was also found that the primary spinel formed via a solid-state reaction was in the nano size range and possessed a cubic morphology. The importance of the present study is explained with an emphasis on refractory applications.
