Abstract

The article presents results of a study on linear and nonlinear dielectric properties of lead zirconate-based ceramics synthesized from precursor powders of PbO and ZrO₂ with particle sizes of 500 nm and 20 nm, respectively. It was established that the addition of 5 mol% of lithium niobate induces a transformation from the antiferroelectric (AFE) to the ferroelectric state. Besides, the use of nanodispersed powders enables a reduction in sintering temperature compared to conventional technical ceramics.
