Summary:A family of new lead-free materials with the general formula Bi[Me.sub.2/3][Sb.sub.1/3][O.sub.3] (Me = Mg, Ni, Co, Zn) have been synthesized using the standard ceramic technology. The temperature dependences of the permittivity ζ' have been studied at frequencies from 0.5 to 1000 kHz in the temperature range from 300 to 800 K. At high temperatures, the permittivity ζ' of the Ni-, Mg-, Co-, and Zn- containing materials has been found to exhibit maxima (at 765, 768, 748, and 780 K, respectively) related to structural phase transitions, which has been confirmed by the measurements of the elastic, inelastic, and thermal properties.
