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.
