摘要：
We present the thermal properties of the proton conducting orthorhombic BaCeO3 by the means of a Rigid Ion Model (RIM). We report the cohesive energy (phi), Reststrahlen frequency (upsilon), Debye temperature (theta(D)) and Gruneisen parameter (gamma). The value of Gruneisen parameter (gamma), which supports the earlier, reported values. Besides, the specific heat values presented in this work by using RIM are in reasonable agreement with the available experimental data for BaCeO3 at low temperature (2K <= T <= 300K).
