Abstract

The equilibrium between liquid III group metal and B2O3 flux was studied thermodynamically. By measuring the oxygen contents in gallium melt and Ga2O3 contents in B2O3 flux, the oxygen distribution ratio between gallium and B2O3 flux and the activity of Ga2O3 in B2O3 flux were clarified at 1373 and 1273 K. The standard free energies of formation of GaBO3 and InBO3 were determined by measuring oxygen content of liquid III group metal (gallium or indium) equilibrated with B2O3 flux and GaBO3 or InBO3.
