Subsolidus phase relations had been determined for the Bi2O3–CuO–Ta2O5 (BCT) system over the temperature range 700–950 °C in air. Two structurally distinct ternary phases of different symmetries, a cubic pyrochlore and a monoclinic zirconolite were observed. Phase-pure pyrochlores existed in a uniqu...
