The conductivity of the films at 700 ° C 2.5 -3 times smaller than the ceramic samples of the respective compositions. At the same time, the activation energy of the films below , whereby the difference of the conduction films and ceramics decreases with decreasing temperature . The obtained skandievmisni thick films have conductivity : the system (ZrO2) 0.80 (Sc2O3) 0.07 (CeO2) 0.06 at 600 ° C - 4 x 10-4 S / cm at 700 ° C - 5.6 ? 10-4 S / cm ; System (ZrO2) 0.90 (Sc2O3) 0.07 (Fe2O3) 0.03 600 ° C - 2.4 x 10-3 S / cm at 700 ° C - 3 x 10-3 S / cm ; wherein the electron conductivity is 2 orders of magnitude lower as compared with the conductivity of oxygen .
