The effect of sintering temperature on the relative density, grain size, pore size, phase content balance, and electrical conductivity of the 6 𝑚𝑜𝑙% 𝑆𝑐 ! 𝑂 " -1 𝑚𝑜𝑙% 𝐶𝑒𝑂 ! 𝑐𝑜 -𝑑𝑜𝑝𝑒𝑑 𝑍𝑟𝑂 ! has been investigated. The samples' density reached the density plateau at 1500 °C while at T>1500 °C densification process stopped and coarsening happened. Then XRD and Raman spectroscopy revealed the presence of minor monoclinic phase for samples sintered at 𝑇 < 1200 °𝐶 which decreases with increase in 𝑇 : . The presence of the cubic phase increased by increase in the sintering temperature. The EIS spectra of the fine-and coarse-grained structures were investigated using circuits consist of R-C and R-CPE elements. The effect of the inductive load has been discussed in interpretation of the Nyquist spectra at intermediate and high temperatures. The total electrical conductivity was measured and presented in an Arrhenius plot.
