对ｘ Ｐｂ（ Ｙ１／２ Ｎｂ１／２ ） Ｏ３ｙ Ｐｂ Ｔｉ Ｏ３ｚ Ｐｂ Ｚｒ Ｏ３ 三元系陶瓷材料进行了研究，对其压电与介电性能进行了测量，发现该三元系材料在 ｘ＝ ０．２～０．５，ｙ＝ ０．４３～０．４６，ｚ＝ ０．５５～０．５８ 具有优异的压电性能，在该范围内，陶瓷材料的居里点在 ４００ ° Ｃ以上。实验表明该材料是一种具有良好应用前景的压电材料。
The trinary system x Pb(Y 1/2 Nb 1/2 )O 3 y PbTiO 3 z PbZrO 3 ceramics material has been investigated.By measuring the piezoelectric and dielectric constants of the ceramics,it is found that this trinary system has attractive piezoelectric peroperties when x=0.2～0.5,y=0.43～0.46,z =0.55～0.58,and its curie temperature is above 400 °C in this range.The experimental results show that the trinary system ceramics is a promising candidate for use as piezoelectric materials.
