Barium titanate/calcium orthodititanate composite ceramic as well as preparation method and application thereof
The invention belongs to the technical field of piezoelectric materials, and particularly relates to barium titanate/positive calcium dititanate composite ceramic and a preparation method and application thereof. The invention provides a BaTiO3/Ca3Ti2O7 composite ceramic. The BaTiO3/Ca3Ti2O7 composite ceramic is prepared from Ca3Ti2O7 and BaTiO3, the molar ratio of the Ca3Ti2O7 to the BaTiO3 is (1 to 3): (7 to 9). The mechanical stress generated by deformation of the composite ceramic under an external driving electric field is effectively regulated and controlled through the components and the component proportion of the composite ceramic, so that the deformation of the composite ceramic is reduced, and the energy storage efficiency and the anti-fatigue performance of the composite ceramic are improved.
本发明属于压电材料技术领域，具体涉及一种钛酸钡/正二钛酸钙复合陶瓷及其制备方法和应用。本发明提供了一种BaTiO3/Ca3Ti2O7复合陶瓷，包括Ca3Ti2O7和BaTiO3；所述Ca3Ti2O7和BaTiO3的摩尔比为1～3：7～9。本发明通过复合陶瓷的成分和成分比例，有效调控复合陶瓷在外加驱动电场下形变所产生的机械应力，从而降低复合陶瓷的形变，提升复合陶瓷的储能效率和抗疲劳性能。
