Abstract Chemicals having relatively Iow melting points have been used to reduce the required sintering temperature of MnO2-doped Pb0.9875((Zr0.52Ti0.48)0.975Nb0.025. Among these compounds Li2CO3, Na2CO3, B2O3, Bi2O3 and V2O5 are suitable additives for this purpose. The substitution and interstitial properties of the doped ions are discussed in connection with their influences on piezoelectricity and dielectric properties. HighQ m materials and materials with temperature-stability ofQ m could be obtained by Li+ and B3+ or Bi3+ doping. Compensation pair effects are proposed to explain the results. Materials exhibiting aQ m of about 500 with a deviation of less than 10% at temperatures up to 300° C have been prepared for filter use. The sintering temperature is as low as 1070° C.
