Popis: The Dielectric losses are theoretical investigated for CaxSr1-xTiO3 and PbxSr1-xTiO3 single crystal perovskites in paraelectric phase as a function of composition and temperature. In our calculation, the Silverman Joseph`s Hamiltonian augmented with fourth order phonon co-ordinates using double time temperature dependent Green`s Function technique is used. Dielectric loss is estimated for various value of x. The substitutional impurity depend dielectric losses increases with increases in composition x at room temperature and Dielectric loss tangent (tan δ) increases with increasing temperature at constant values of x.
