摘要：

The Bi2O3-CdO-CdF2 system was investigated by means of X-ray diffraction at temperatures between 630 and 800-degrees-C. Four solid solution domains were characterized, corresponding respectively to anti-alpha-AgI, Bi-Sr-O rhombohedral (epsilon), A-La2O3 and fluorite structural types. Among these phases, the most attractive conductivity performances were evidenced in the fluorite domain (sigma = 2 x 10(-5) S cm-1 at 300-degrees-C for Bi0.42Cd0.58O0.72F0.97) and were shown to depend on the oxygen-fluorine ratio.
