摘要：
The effect of the sintering temperature of the Ce0.8Gd0.2O2-delta + 2 mol % TiO2 on its microstructure, electric, and optical properties was studied using the methods of x-ray spectroscopy, scanning electron microscopy (SEM), conductivity and ellipsometry. It is shown that the electrolyte lattice parameter decreases at an increase in the sintering temperature. The pattern of the sample surface obtained using the SEM method points to the dominating role of the sintering temperature in the formation of the electrolyte microstructure. Variation of optical properties as dependent on the synthesis temperature is also determined by the microstructure parameters of ceramics: presence of pores, formation of grain interfaces.
