Using combined resonance and ultrasonic methods, a full set of material constants has been measured for morphotropic phase boundary (MPB) composition xPb(In(12)Nb(12))O(3)-(1-x-y)Pb(Mg(13)Nb(23))O(3)-yPbTiO(3) (PIN-PMN-PT) single crystals poled along 001. Compared with the MPB composition (1-x)Pb(Mg(13)Nb(23))O(3)-xPbTiO(3) (PMN-PT) single crystals, the PIN-PMN-PT single crystals have smaller anisotropy, higher Curie temperature (T(c) approximately 197 degrees C), and higher rhombohedral to tetragonal phase transition temperature (T(R-T) approximately 96 degrees C). The electromechanical properties obtained here are the best found so far for this ternary system with d(33) approximately 2742 pCN, d(31) approximately -1337 pCN, k(33) approximately 95%, and k(31) approximately 65%.
采用共振和超声相结合的方法,对沿001极化的准同型相界(MPB)成分xPb(In(12)Nb(12))O(3)-(1-x-y)Pb(Mg(13)Nb(23))O(3)-yPbTiO(3)(PIN-PMN-PT)单晶测量了全套材料常数。与MPB成分(1-x)Pb(Mg(13)Nb(23))O(3)-xPbTiO(3)(PMN-PT)单晶相比,PIN-PMN-PT单晶具有较小的各向异性、较高的居里温度(Tc约197℃)和较高的菱方相到四方相转变温度(TR-T约96℃)。这里得到的机电性能是迄今为止在该三元体系中发现的最佳性能,d(33)约2742 pCN,d(31)约-1337 pCN,k(33)约95%,k(31)约65%。
