ABSTRACT:
Lead zirconate titanate ceramics comprise from about 92 to 99.0 weight pent of lead zirconate and lead titanate in ratio from 0.505 to 0.54:0.495 to 0.46 respectively, from about 0.5 to about 2 weight percent of one or more fluorides or chlorides of an alkali metal or alkaline earth except francium or radium, and 0.5 to 6 weight percent of one or more oxides of magnesium, barium, chromium, scandium, aluminum, lanthanium, praesodymium, neodymium or samarium. The ceramic after pressing is annealed at a temperature from about 1050.degree. to 1350.degree. C. Ceramic elements made from the above ceramics are useful as sonar and microphone transducers.
