Abstract
The oxidation behavior of palladium, ruthenium and iridium powders of different grain sizes was investigated by TG, DTA and X-ray methods. The solid oxides formed during heating up (PdO, RuO 2, IrO 2) show different stability and decomposition temperatures depending on the oxygen pressure. The kinetics of the reaction MeO x → Me+ x/2 O 2 is discussed. High temperature X-ray studies confirmed the strong anisotropy of thermal expansion in the case of RuO 2 and IrO 2. The thermal expansion behavior of these oxides is compared to that of other rutile-type oxides.
