Abstract
The phase formation in the CdO-rich part (≤10 wt % Bi2O3) of the CdO–Bi2O3 system was studied by x-ray diffraction, IR spectroscopy, electron microscopy, and other techniques. The results indicate that the grinding of the starting powder mixtures in a planetary mill leads to an inhomogeneous Bi2O3 distribution and a high defect density in the CdO and Bi2O3 particles. Sintering in the range 910–990 K gives rise to the formation of the γh phase, whose content depends strongly on the mixture composition and sintering conditions. At sintering temperatures above its melting point, the γh phase acts as a binder of CdO grains.
