采用热锻法和热晶生长法合成了致密的(1−x)Pb(In1/2Nb1/2)O 3-xPbTiO 3(PIN-PT)陶瓷。用X射线衍射法和介电测量研究了(1−x)PIN-xPT相图。当PT含量较低时，相界区域介于三方相区和较高含量时的四方相区之间，即在0.34-0.39X范围内。在室温下，当x=0.37时，观察到四方相和可能的单斜相的混合物。
Dense (1−x)Pb(In1/2Nb1/2)O3–xPbTiO3(PIN–PT) ceramics were synthesised by hot forging and thermal grain growth. (1−x)PIN–xPT phase diagram was investigated by X-ray diffraction and dielectric measurements. The morphotropic phase boundary zone was found to be between a rhombohedral phase region for low PT contents and a tetragonal phase region for high PT contents, i.e. in the 0.34–0.39x range. A mixture of tetragonal and probably monoclinic phases was observed for x=0.37 at room temperature.
