THERMODYNAMIC INVESTIGATION OF CERAMIC MATERIALS AT ELEVATED TEMPERATURES
Abstract
Structures investigated were FeO, TiO, VO, and NbO (all NaCl structure). They belong in 2 groups: One group is FeO where only iron vacancies are present. The other group is TiO, VO,AND NbO where both anion and cation vacancies can be found. In both groups the concentration of vacancies is quite large. First, mathematical expressions for the interaction energy between vacancies were derived. In the compounds investigated, the defects occurred only as vacancies exhibited by both components. The grand partitionnction for a cstal with only vacancies present is presented. (Author)
