Preparation method of high-performance potassium-sodium niobate-based lead-free energy storage ceramic
The invention belongs to the field of dielectric capacitor materials, and particularly relates to a preparation method of high-performance potassium-sodium niobate-based lead-free energy storage capacitor ceramic. The potassium-sodium niobate-based ceramic powder is obtained from industrial raw materials through a solid-phase method, a ceramic sample is obtained through unique two-stage sintering,and the energy storage density of the sample is obtained through ferroelectric hysteresis loop testing and calculation. Firstly, the ball milling time of ceramic powder and the two-stage sintering schedule of a green body are adjusted, and then the effective energy storage density and efficiency of the ceramic powder are obtained through ferroelectric analysis. The preparation method of the potassium-sodium niobate-based energy storage ceramic material is simple, convenient and capable of effectively obtaining high energy storage density and efficiency, and has reference significance for preparation of energy storage ceramic materials of other systems.
