DIELECTRIC SPECTROSCOPY OF MULTICOMPONENT HIGH SENSITIVITIES FERROCERAMICS BASED ON PZT SYSTEM
Multicomponent highly sensitive ferroelectric ceramic materials based on the PZT system were obtained using conventional ceramic technology. It was found that all solid solutions have a perovskite structure, and the relative densities of the samples fluctuate in the range (92 ÷ 95)%. The dielectric properties of the obtained ceramics were studied inthe temperature range (300 ÷ 800) K, frequencies of the alternating electric field (25 ÷ 2•106) MHz. It is shown that the obtained materials have stable dielectric properties in a wide temperature range, with practically no hysteresis of the Curie temperature. The reasons for the revealed regularities are discussed.
