The subsolidus phase diagram CaO-Al 2 O 3 -Ta 2 O 5 has been determined at 1300-1350Β°C. Two ternary phases are present, Ca 2 AlTaO 6 and the new phase, CaAlTaO 5 . From Rietveld refinement of powder X-ray diffraction data, CaAlTaO 5 has the sphene structure, monoclinic 6.6760(3), 8.9546(3), 7.3494(3
