Oxygen partial pressure in equilibrium with nonstoichiometric ceric oxide of a definite composition were determined by equilibration with pure oxygen, air, CO2, and CO2-H2 mixtures at 900, 1000, 1100, 1227, and 1300°C, using a thermobalance. The values for the activities and the relative partial enthalpies and entropies of both Ce2O3 and CeO2 were calculated on the basis of the relation between the Po2 and its composition.
A stoichiometric compound, Fe1.000O, was synthesized at high pressures above 36 kbar at 770°C by a reaction between Fe0.950O and metallic iron. The cell dimension of Fe1.000O was determined to be 4.323±0.001 Å at atmosphere pressure.
The solubility of hydrogen chloride in volcanic rock melts was experimentally determined at mixed with nitrogen under one atmosphere. The solubility of hydrogen chloride decreases not only with a rise in the temperature, but also with an increase in the silica content of volcanic rock melts, while it increases with an increase in the partial pressure of hydrogen chloride. The equilibrated concentration of chlorine obtained by experiments was compared with those in natural basalts collected from Japan and Hawaii.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
