High-voltage gradient zinc oxide voltage-sensitive ceramic and preparation method and application thereof
The invention discloses a high-voltage gradient zinc oxide voltage-sensitive ceramic and a preparation method and application thereof, and belongs to the technical field of functional voltage-sensitive ceramics and preparation thereof. According to the invention, the problem that the existing ZnO voltage-sensitive ceramic cannot realize the high voltage gradient characteristic is solved. According to the preparation method, Fe2O3, Li2O and ZnO are compounded, so that the ZnO voltage-sensitive ceramic with high voltage gradient is obtained by comprehensively utilizing the grain resistance and the grain boundary barrier layer to induce and improve the voltage-sensitive characteristic of the ZnO ceramic while the quantity of components of the ZnO voltage-sensitive ceramic is ensured to be as small as possible. Besides, the high-voltage-gradient ZnO voltage-sensitive ceramic provided by the invention has a simple component number, and the voltage-sensitive voltage of the doped ceramic can be effectively regulated and controlled by adjusting the addition amount of Fe2O3 and Li2O, so that the high-voltage-gradient ZnO voltage-sensitive ceramic is obtained.
