Effect of Doping ZrO_2 on the Properties of (CeO_2)_(0.86)(SmO_(1.5_)_(0.14) Ceramics
Source abstract
Abstract
The effect of doping ZrO2 on the electrical conductivity and strength of CeO2/Sm2O3 ceramics was investigated, and the microstructure of samples was studied and analyzed by means of XRD and SEM. The results showed that doping ZrO2 could decrease the electrical conductivity. It was attribute to the reason that solution of ZrO2 in ceria-based electrolyte reduced the lattice constant. Doping ZrO2 increased the fracture strength and the fracture was intergranular for the reason that ZrO2 toughened the grain-boundary. Ceramics doped with ZrO2 were dense as well. (CeO2)0.86(SmO1.5)0.14 doped with 2.5mol% ZrO2 may be a potential electrolyte material used for SOFC for its proper electrical conductivity and strength.
