Influence of twin cations on zirconia composites stability

Last years the ternary stabilised zirconia systems attract a considerable attention as a source of materials for structural ceramics as well as for modern fuel cells. The simultaneous influence of a pair of cations (twinned) such as: Mg 2+–Ca 2+ and Sr 2+–Ca 2+ on zirconia powders stabilisation proc...

Description
Summary:Last years the ternary stabilised zirconia systems attract a considerable attention as a source of materials for structural ceramics as well as for modern fuel cells. The simultaneous influence of a pair of cations (twinned) such as: Mg 2+–Ca 2+ and Sr 2+–Ca 2+ on zirconia powders stabilisation process in 1550–1750 °C temperature range. Samples for investigations were performed by classical ceramic method. Comparative microstructure investigations were made by SEM on sample surfaces. The XRD, FTIR analysis and EDS spectra for the considered samples are in good agreement with the determined properties of the studied compositions.
