Abstract

The thermal behaviour of coprecipitated hydroxide mixtures leading to the synthesis of MgAl₂O₄ spinel powders has been investigated. The mixtures of hydroxides have been prepared by coprecipitation reaction from nitrate solutions with a molar ratio for Mg/Al of 1:2. The results have been related to the thermal behaviour of separately precipitated components of the hydroxide mixtures. The different steps in the thermal decomposition have been characterized via X-ray diffractometry (XRD). A mechanism for the spinel formation from the thermal decomposition of the hydroxide mixtures has been hypothesized.
