The crystalline phases in the system (Ba, Ca) (Ti, Zr)O 3 were identified and their lattice dimensions were determined from X‐ray powder patterns of fired ceramic disks. Compositions near the BaTiO 3 ‐BaZrO 3 and CaTiO 3 ‐CaZrO 3 sides of the composition square gave evidence of complete solid solution, whereas all intermediate compositions contained two separate phases. Variations in the temperature of the Curie point and in aging rate were found to correlate reasonably well with variations in the character of the crystal structure.
