title: Phase Equilibria and Crystal Chemistry in Portions of the System SrO-CaO-Bi2O3-CuO, Part IV- The System CaO-Bi2O3-CuO.
abstract: New data are presented on the phase equilibria and crystal chemistry of the binary systems CaO-Bi2O3and CaO-CuO and the ternary CaO-Bi2O3-CuO. Symmetry data and unit cell dimensions based on single crystal and powder x-ray diffraction measurements are reported for several of the binary CaO-Bi2O3phases, including corrected compositions for Ca4Bi6O13and Ca2Bi2O5. The ternary system contains no new ternary phases which can be formed in air at ~700-900 °C.
