Abstract : PHASE STUDIES), (*TITANATES, PHASE STUDIES), (*RESONATORS, PIEZOELECTRIC CRYSTALS), SOLID SOLUTIONS, TABLES(DATA), PEROVSKITES, PHASE DIAGRAMS*LEAD TITANATE ZIRCONATE CERAMIC MIXES, *LEAD TITANATESA survey is given on the development of piezoelectric lead zirconate titanate ceramics by the addition, modification, and substitution of lead niobate. Work by this laboratory, aimed at improved ceramic resonator materials, is reported in particular, additions of lead barium niobates to lead zirconate titanate. The limited solid solubility of lead barium niobate in lead zirconate titanate was found responsible for the poor piezoelectric response observed with these ceramics. A literature survey indicates that the widest range of solid solution with useful piezoelectric properties is formed by substitution of lead niobates with perovskite structure into lead zirconate titanate with tetragonal or rhombohedral structure.
