The article presents the results of a study of the dielectric properties and harmonic coefficient of lead zirconate-based ceramics synthesized at different sintering temperatures from the initial PbO and ZrO? powders with particle sizes of 500 and 20 nm, respectively. It has been established that the use of nanodispersed powders makes it possible to reduce the sintering temperature compared to traditional technical ceramics made from 1 ?m particles. The maximum value of the dielectric constant was recorded for ceramics sintered at a temperature of 1100 °C. With an increase in the sintering temperature above 1200 °C, a decrease in the dielectric constant is observed, however, upon cooling in the range of 226…208 °C, a ferroelectric phase is formed.
