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.
