Abstract
The first-order Raman spectra of sintered body-centered BaWO4 crystalline are measured at room temperature. The phonon dispersion curves of BaWO4are calculated on the basis of a rigid-ion model using the measured frequency values. The temperature dependence of the phonon specific heat capacity, and the elastic constants of BaWO4 are calculated using one-phonon density of states and three acoustic phonon frequencies obtained from phonon dispersion curves, respectively.
