In this work, we showed that doping of sesquioxide based ceramics (for instance, Y2O3) by heterovalent ions leads to altering of polarizations. It results in variation of refractive index and wave-front distortion due to presence of volumes with increased content of heterovalent ions. It also contributes to lowering of transmittance and increasing of scattering in ZrO2-, HfO2-, or CeO2-doped Y2O3 ceramic samples.
