چکیده انگلیسی
Sr1-xLaxTiO3 (SLT; 0â¯â¤â¯xâ¯â¤â¯0.5) powder samples were synthesised at room temperature by a mechanochemical method from SrO, La2O3 and TiO2 mixtures in 90â¯min. The obtained SLT samples as potential anode materials in solid oxide fuel cells (SOFCs) were investigated. The microstructure, electrical conductivity and chemical compatibility with yttria-stabilised zirconia (YSZ) were studied. The powder samples had a nanometric character after milling. After a subsequently heating at 900â¯Â°C, the particle size slightly increased, but still remained nanometric. At this high temperature, a good chemical compatibility with YSZ was found. The xâ¯=â¯0.2 sample gave the best electrical conductivity values, i.e. 0.23â¯Wâ¯cmâ2. These features make such as-obtained samples good candidates to be used as anodes in SOFCs.
