摘要：

At room temperature the sequence of phases with increasing amounts of strontium in the system CaTiO3/SrTiO3 is orthorhombic (Pnma), orthorhombic (Bmmb), tetragonal (I4/mcm), and cubic (Pm3m). All phase boundaries shift toward smaller strontium contents with increase of temperature. Volume changes resulting from phase transformations are small for all compositions. Shape changes are greatest (similar to 0.3%) for the Bmmb/I4/mcm transition, but would probably be accommodated by microtwinning and so are unlikely to affect the mechanical integrity of a specimen.
