Synthesis, structure, microstructure, and electrical conductivity of (La,Sr)(Ga,Mg)O3-δ Oxide-ion-conducting ceramics

Oxide-ion-conducting perovskite ceramics (La1-ySry)(Ga1-xMgx)O 3-δ were prepared using hydrated Mg and La salts as starting reagents. X-ray diffraction and IR spectroscopy data demonstrate that the symmetry of the solid solutions changes in the sequence orthorhombic-rhombohedral-cubic with increasing Sr + Mg content. © 2001 MAIK "Nauka/Interperiodica".
