Abstract:
The phase compositions of finely dispersed initial and rehydrated products of gibbsite thermal activation prepared by different technological methods - thermochemical activation (TCA) and centrifugal thermal activation (CTA) were studied using radial distribution function (RDF) method. The initial phase composition was shown to depend on the preparation method and determine the composition of the rehydrated products. Nuclei of different hydroxide phases are formed in addition to chi-alumina - pseudoboehmite in the case of the TCA process and bayerite for the CTA process. This leads to different phase compositions of rehydrated products. For TCA, pseudoboehmite is the primary rehydration product, whereas bayerite is formed for CTA.
