The sintered samples were studied through x-ray diffraction (XRD), scanning electron microscopy (SEM), and electron dispersive spectroscopy (EDS) analyses. The microstructure observations revealed that the samples were near fully dense at a sintering temperature of 1200°C for 1h. The samarium doping prevented accelerated grain growth of the SnO2-based ceramic in the final stage of the sintering. The mean grain size of the SnO2-based ceramic without Sm2O3 doping was 2.70µm, which was reduced to 0.887µm for the sample doped with 0.05mol% Sm2O3. The grain size reduction of samples doped with Sm2O3 could be attributed to the segregation of Sm2O3 at the grain boundaries.}, keywords = {Samarium Oxide,Tin Oxide,Rare earth,Segregation,Sintering,Nanosized Materials}, url = {https://www.acerp.ir/article_95730.html}, eprint = {https://www.acerp.ir/article_95730_e02fc880f653d46e3d36dde23e89b55b.pdf} }
