The electrocaloric effect (ECE) of Tin Titanate (SnTiO 3 ) has been investigated in the present manuscript. A phenomenological model has been adopted for predicting electric polarization variation with temperature to examine electrocaloric properties such as entropy change, heat capacity change and relative cooling power. The results indicate the potential of this ferroelectric compound to achieve the ECE near Curie temperature ( T C). It is useful as prospective candidate for cooling system in a wide temperature interval. The maximum change in entropy near  T Cobtained by phenomenological model has been compared with the value procured by Tarnaoui  et al.  [ 1 ]. The results confirm that the phenomenological model is undoubtedly beneficial for the prediction of the electrocaloric effect of ferroelectric materials.
