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.
