Thorium-acetate and thorium-propionate complexes

Journal of Inorganic and Nuclear Chemistry, 1972
Abstract Equilibrium of complexes formation has been studied for the systems thorium-acetate and thorium-propionate at 25°C and ionic strength 1·0. At the experimental conditions only the first stability constant was possible to determine, using the potentiometric and spectrophotometric methods, which gave results in good agreement.

Alloys of thorium with certain transition metals II. The systems thorium-osmium, thorium-iridium and thorium-platinum

Journal of the Less Common Metals, 1964
Abstract The thorium-osmium, thorium-iridium and thorium-platinum binary systems have been studied over the whole range of compositions in the temperature range 1000°-1500°C mainly by metallographic and X-ray methods. Intermetallic compounds occur in each system and solid solubility in thorium at 1000°C is very low.

Thorium-thorium dioxide phase equilibria

Journal of Nuclear Materials, 1969
Various Th-ThO2 mixtures were investigated with thermal analysis, X-ray, and microscopic techniques. The following information on phase boundaries is deduced. The oxygen solubility in solid Th is less than the OTh ratio of 0.003. The solid-solid transition of Th saturated with ThO2 occurs at 1370 ± 30 °C.
