IDENTIFICATION OF SECOND PHASE DEPOSITED ON La-DOPED SrTiO3 PEROVSKITES SYNTHESIZED BY CITRIC-GEL METHOD

We examined deposition process of the second phase during sintering Sr 0.7 La 0.3 TiO 3 perovskite at 1400°C and analyzed the detailed composition by means of SEM-EDX technique. The second phase deposited at the corners of the Sr 0.7 La 0.3 TiO 3 matrix grains was confirmed to be Sr-doped rare-earth B-type La 2 O 3 .
