CHEMICAL THERMODYNAMICS OF MATERIALS AT HIGH TEMPERATURES

Abstract

The activities of Ga and In are to be determined as a function of the composition of the 2-component system, Ga-In. An investigation of the Sc-H and Y-H systems is in progress. The present effort is aimed at the establishment of the thermodynamic properties of the systems and construction of the phase diagrams. For this purpose, equilibrium H pressure-temperature-composition data are obtained. The behaviors of the Sc-H and Y-H systems are similar, with the equilibrium pressures in the Sc-H system being higher than those of the Y-H system. Experimental work was completed on the volume of mixing of noninteracting spheres of various radius ratios. Glass beads, 126 to 222 microns in diameter were used.
