Structural and electrical properties of lanthanide substituted-bismuth titanate prepared by low-temperature combustion synthesis

This paper elucidates the structural and electrical properties of Bi4Ti3O12 (BIT), Bi3.25Nd0.75Ti3O12 (BNT075) and Bi3.25La0.75Ti3O12 (BLT075) compounds that were primarily prepared by a novel combustion route at temperature as low as 300oC. Single crystalline phase of bismuth-layered perovskite...
