Solid electrolytes based on Sm2O3-doped Ceria were prepared by the sol-gel mehod.Average grain size and lattice constant in prepared electrolyte materials were analyzed by X-ray diffraction technique
and conductitivities of the samples were measured by using impedance spectroscopy.The results show that the powder samples have cubic fluorite-type structure
smaller grain size and average grain size less than 40nm
lattice constant of the samples greater than that of pure CeO2.Conductivity of the samples of the...
