N2 - (1 − x)(0.1BiYbO3–0.9PbTiO3)–xPb(Yb0.5Nb0.5)O3 (PYN-BYPT) ceramics were prepared by the conventional solid state reaction. The effect of Pb(Yb0.5Nb0.5)O3 content on the microstructure and electrical properties of ceramics was investigated. The results show that there are two phases, perovskite phase and pyrochlore phase (Yb2Ti2O7), coexisting in PYN-BYPT ceramics when the content of Pb(Yb0.5Nb0.5)O3 increases from 0.1 to 0.3 mol. With increasing Pb(Yb0.5Nb0.5)O3 content, the pyrochlore phase Yb2Ti2O7 increases, TC decreases and d33 increases firstly and then decreases. When the content of Pb(Yb0.5Nb0.5)O3 increases from 0.4 to 0.9 mol, perovskite phase and pyrochlore phase (Pb2Nb2O7) coexists in the ceramics. The contents of Pb2Nb2O7 and the TC decrease. PYN-BYPT ceramics with 0.2 mol Pb(Yb0.5Nb0.5)O3 show the optimal piezoelectric properties, with εr of 231.4, tanδ of 0.015, d33 of 20 pC/N, and TC of 523.2 °C, which makes it a promising material for high-temperature (up to 500 °C) piezoelectric applications.
