摘要：

Substitutions of B-sites by Ti in several Pb-based perovskite ceramics that had high relative permittivities (epsilon(r)), high Q values, and small temperature coefficients of resonant frequency (tau(f)) were studied in order to control epsilon(r) and tau(f) independently. It was found that relative permittivities with near-zero tau(f) in (Pb, Ca)(Zr, Ti)O3, (Pb, Ca) {(Fe1/2Nb1/2), Ti}O3, and (Pb, Ca){(Mg1/3Nb2/3), Ti}O3 systems could be controlled in the epsilon(r) regions lower than 105, 95, and 70, respectively. All these systems had sufficiently high Q values. They are applicable to resonant devices for mobile communications.
