As for CaZrO 3 (CZ) ceramic, the reported dielectric property values, especially dielectric constants, were much different from 23 to 32, which is reliable and credible? Without precise property data, CZ can’t be further developed and utilized accurately. Herein, CZ ceramic was fabricated by a traditional two-step sintering process, then simulated and calculated the dielectric properties precisely at a microscopic polarization angle using the lattice vibrational spectra and the Clausius–Mossotti (C–M) as well as damping equations. The Raman and Fourier transform far-infrared modes were analyzed and used to predict the intrinsic properties, which were consistent well with the values calculated from C–M and damping equations. The intrinsic permittivity, after precise prediction, is about 20, which is reliable and credible. As for the dielectric loss, the value of about [Formula: see text] was obtained after precise calculation, which is similar to other results.
