## Abstract Lanthanum silicate oxyβapatites are thought of as ytrriaβstabilized zirconia substitutes in intermediate temperature solid oxide fuel cells. Lanthanum silicate oxyβapatite powders La~9.33~Si~6~O~26~ are successfully synthesized at lower temperature by a moltenβsalt method. Xβray diffrac
In the past years, a major interest has been devoted to decrease the working temperature of solid oxide fuel cells (SOFCs) down to about 700 β’ C. Apatite materials (La 10-x Sr x Si 6 O 27-x/2 ) are attractive candidates for solid electrolytes, with a high ionic conductivity at 700 β’ C, a chemical a
