Subsolidus phase relations in La_2O_3-Bi_2O_3-CuO

摘要

The subsolidus phase relations in the ternary system La_2O_3-Bi_2O_3-CuO at 900deg.C were investigated by X-ray powder diffraction. A new binary compound, Bi_2La_4O_9, was found, as well as a binary and a ternary solid solution series, Bi_1-xLa_xO_1.5 (0.16≤x≤0.33) and La_1-xBi_xCuo_4 (O≤x≤0.11), respectively.
