Abstract

The structure of tantalum oxide hydrate derived from peroxo poly-tantalate was investigated on the basis of XRD analyses. The peak positions in the pair distribution functions (PDF) for as-prepared and postannealed samples correspond with those calculated from the crystalline l-Ta₂O₅. Microcluster models for each sample were constructed and the validities of these models were confirmed by comparison between their calculated PDFs and their observed ones.
