CERAMIC CAPACITOR HAVING A DIELECTRIC OF (PB,LA)(ZR, TI)O3 AND BATIO3

摘要

A ceramic capacitor has a dielectric body having a major proportion of an antiferroelectric lead lanthanum zirconate titanate (PLZT) and a minor proportion of a barium titanate. The body may also include up to 10 weight percent of a low melting flux, which is especially useful in monolithic ceramic capacitors having buried silver-containing electrodes. These dielectric bodies exhibit at moderate voltage stress levels an improved combination of properties including a high dielectric constant that is relatively stable with changing voltage and temperature.
