Dielectric and ferroelectric properties of BaBi4Ti4O15 ceramics and their dependence on lattice structure
|
Abstract:
Good quality barium bismuth titanate (BaBi 4Ti 4O 15 ) ceramics is fabricated successfully with BaBi 4Ti 4O 15 nano powders prepared by Sol-Gel process. The ferroelectric to paraelectric phase transition of barium bismuth titanate ceramics was studied by determining the dielectric and saturated ferroelectric properties of barium bismuth titanate. All measurements show barium bismuth titanate may be a kind of order_disordered relaxor ferroelectrics with a diffused phase transition which is a first ordered one, and its dielectric and saturated ferroelectric properties depended strongly on its lattice structure.
