研究了钛酸锶铅在整个摩尔分数范围内实现固溶体的介电、热性能和晶格尺寸。研究发现，钛酸铅·锶与钛酸铅·钛酸锶和钛酸锶铅一样具有铁电性。随着Sr2+含量的增加，晶格体积和四方性减小。居里温度随Sr2+含量的增加而线性下降，没有观察到其他的转折点。居里-魏斯公式在居里温度以上成立，居里常数值为(3∼9)×104°C。
The dielectric and thermal properties and lattice dimensions of lead·strontium titanate were investigated, the solid solution being realized in the whole range of molar percentage. It was found that, lead·strontium titanate is also ferroelectric as lead·barium titanate and barium·strontium titanate. As the content of Sr 2+ increases, the lattice volume and tetragonality decrease. The Curie temperature decreases linearly with the increase of the content of Sr 2+ and any other transition point was not observed. Curie-Weiss formula holds above Curie temperature, the value of Curie constant being (3∼9)×10 4 °C.
