Strontium Bismuth Tantalate Ceramic

Using bitao 4 as the precursor ferroelectric strontium bismuth tantalate srbi 2 ta 2 o 9 was successfully synthesized.

Strontium bismuth tantalate ceramic. These films however have a critical problem. Ferroelectric and piezoelectric properties of strontium bismuth tantalate ceramics p 1169. Strontium bismuth tantalate sbt ferroelectric thin films have attracted considerable attention for the de velopment of non volatile ferroelectric random access memories nv frams. Strontium bismuth tantalate sbt thin films containing sr defect and bi excess have been prepared by chemical solution deposition onto spontaneously oxidized si 100 substrates with two different heterostructure electrodes.

Jacers is a leading source for top quality basic science research and modeling spanning the diverse field of ceramic and glass materials science. Strontium bismuth tantalate strontium bismuth tantalum oxide sbt is a ferroelectric ceramic for dielectric applications in electronics and other advanced technologies. Sr deficient and bi excess sbt sr 0 8 bi 2 2 ta 2 o 9 s 0 8 b 2 2 t ceramic samples were prepared by a conventional ceramic technique. Layered perovskite sbt films were crystallized in oxygen by rapid thermal processing at 973 k for 1 h with an intermediate treatment at 823 k for 2 h.
