SBTI

Meanwhile , the good thermal stability of SBTi is not deteriorated .

同时，保持了SBTi良好的热稳定性能。

SBTi thin films with enhanced a-axis orientation were prepared on Pt / Ti / Si02 / Si substrates by the Sol-Gel method .

采用溶胶凝胶工艺，在Pt/Ti/SiO2/Si基片上制备了a轴取向增强的SBTi铁电薄膜。

The dielectric constant of ferroelectric ceramics from room temperature to 200 ℃ can be increased properly by adding Ag , but the dielectric loss of the SBTi / Ag composites remains unchanged .

Ag的加入可以适当提高铁电陶瓷从室温到200℃的介电常数，但对材料的介电损耗影响很小。

A-sites in perovskite unit of SBTi are occupied by two kind of cations , trivalent Bi ~ 3 + and divalent Sr ~ 2 + .

SBTi类钙钛矿层的A位含有两种阳离子：三价的Bi~（3+）和二价的Sr~（2+）。

Vanadium-doping with appropriate content enlarges the remnant polarization ( 2P_ r ) and enhances the electric breakdown voltage of SrBi_ 4 Ti_ 4 O_ 15 ( SBTi ) .

适量的钒掺杂，大大增加了SrBi4Ti4O15（SBTi）铁电材料的剩余极化2Pr，并改善了材料的耐压性能。
