Fine grained polycrystalline yttria materials were synthesized either by Hot Isostatic Pressing of a 99.995% pure Y 2 O 3 powder or by pressureless sintering with the addition of a small amount of titanium oxide (≃0.2wt%). Sintered bodies exhibit a

A number of equations have been proposed in the literature to fit the data obtained during compaction of powders. Macroscopic parameters such as the relative density [1], the 'relative volume of the compact' [2], or the 'fractional volume compaction'

The electrical properties of single crystals of yttria-stabilized zirconia [${(\mathrm{Z}\mathrm{r}{\mathrm{O}}_{2})}_{0.88}$-${({\mathrm{Y}}_{2}{\mathrm{O}}_{3})}_{0.12}$], known to be an essentially anionic conductor, are studied in wide ranges of

Infrared reflection spectra of niobium dioxide at room temperature are reported. The results are analysed and compared with existing data concerning oxide crystals with the rutile structure and monoclinic vanadium dioxide which is a parent compound o

The oxygen semipermeability of calcia-stabilized zirconia tubes has been studied up to 2073 K, by determination of the oxygen flow through the electrolyte tube and it is found to be in good agreement with the theoretical expression for the oxygen ele
