Phase formation and properties of doped SBN and SBT solid solutions

Phase formation, structural and electric properties of bismuth layered perovskite like ferroelectric ceramics Sr[Bi 1 - xTb x] 2[Nb 0.9Fe 0.05Cr 0.05] 2O 9 - δ (1) and Sr[Bi 1 - xTb x] 2[Ta 0.9Fe 0.05Cr 0.05] 2O 9 - δ (2) have been investigated. It has been determined that single phase solid solutions are formed at 0.00 ≤ x ≤ 0.04 (1) and 0.00 ≤ x ≤ 0.30 (2). The perovskite-like structure of all solid solutions obtained is characterized by the orthorhombic symmetry. The volume of the unit cell and T C of solid solutions 1 and 2 has been found to decrease with x increasing. © 2012 Elsevier B.V.
