研究了0.59Pb（Mg_（1/3）Nb_（2/3））O_3 - 0.31PbTiO_3 -0.10Pb（Fe_（1/2）Nb_（1/2））O_3（0.59PMN-0.31PT-0.10PFN）陶瓷的结构、介电、铁电和压电性能。研究表明，该复合材料的相结构接近准同型相界，具有优良的电性能。与PMN-PT相比，10%PFN取代导致（i）烧结温度降低;（ii）居里温度升高和特殊的弛豫行为;（iii）低介电损耗，这表明该新型三元体系值得进一步探索。
The structural, dielectric, ferroelectric and piezoelectric properties of 0.59Pb(Mg1/3Nb2/3)O3–0.31PbTiO3–0.10Pb(Fe1/2Nb1/2)O3(0.59PMN–0.31PT–0.10PFN) ceramic have been investigated. The investigations show that its phase structure is near the morphotropic phase boundary, and excellent electrical properties are obtained with this composition. Compared with PMN–PT, studies also show that 10% PFN substitution results in (i) a decreased sintered temperature; (ii) an increased Curie temperature and peculiar relaxation behavior; and (iii) a low dielectric loss, which indicates that the novel ternary system deserves further exploration.
