ABSTRACT

Much work has been performed on characterisation of intermediate phases during calcination and dehydration of various alumina hydrates. The most important factors found to affect transitions between the intermediate phases include the crystal size and morphology of the starting hydrate, the calcination conditions, including temperature, heating rate and atmosphere, and the amount of additives or impurities present.

In this work the calcination routes of three Gibbsites were investigated. The Gibbsites differ in their initial morphology and grain size. The calcined materials were characterised using XRD and SEM.
