At room temperature the sequence of phases with increasing amounts of strontium in the system CaTiO{sub 3}/SrTiO{sub 3} 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 ({approximately}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.
