Abstract
Phase relationships in the section CaGeO3-BaSiO3 in the range 1000-1500°C were studied. Samples were prepared by a solid-phase procedure. The phase relationships were studied by X-ray phase, differential thermal, and crystal-optical (with immersion specimens) analyses and by the annealing-quenching technique. The phase diagram of the system CaGeO3-BaSiO3 was constructred. A discrete variable-composition berthollide phase crystallizing in the walstromite structural type was revealed. No solid solutions based on the extreme members of the system were found. The diagram of phase equilibria in the edge sections of the concentration tetragon CaSiO3-4CaGeO3-BaGeO3-BaSiO3 is presented, and the solubility boundaries are schematically shown for the solid solutions existing in this system at 1200°C.
