Abstract

Phase equilibria in the system CdO-B2O3-GeO2 were investigated at 800° C using X-ray powder diffraction techniques. The binary phases reported previously as produced by solid-state reactions were confirmed and, in addition, a new one CdO·2GeO2 was found. The ternary phase diagram was solved and a new phase CdO·B2O3·GeO2 was discovered. X-ray powder data are given for both these new phases. Solid solution effects were investigated for the primary and binary phases by comparison of patterns; no solid solutions were detected. The relationship of the phase diagram to the composition of photoconductive oxide glasses is discusssed in the light of previous suggestions made of possible mechanisms responsible for the photoelectric effects.
