Energy storage ceramic material and preparation method thereof, and preparation method of high energy storage density ceramic capacitor dielectric
The invention discloses an energy storage ceramic material and a preparation method thereof, and a preparation method of a high energy storage density ceramic capacitor dielectric, the general formula of the energy storage ceramic material is (1-y) (Bi0. 5Na0. 5) (1-x) AxDE3-yG, wherein D is a Ti element, and E is an O element; aDE3 is a modifier general formula capable of improving the stability of Bi0. 5Na0. 5TiO3, so that (Bi0. 5Na0. 5) (1-x) AxDE3 with a morphotropic phase boundary is obtained; g is a relaxation agent general formula capable of being introduced at the morphotropic phase boundary; x is larger than or equal to 0.06 and smaller than or equal to 0.25, and y is larger than 0 and smaller than or equal to 0.18. The Bi0. 5Na0. 5TiO3 modified by the modifier has a more stable structure, and also has a morphotropic phase boundary, so that the performance of the material can be improved by introducing a relaxation agent into the morphotropic phase boundary.
本发明公开一种储能陶瓷材料及其制备方法以及高储能密度陶瓷电容器电介质的制备方法，其中，储能陶瓷材料的通式为(1‑y)(Bi0.5Na0.5)(1‑x)AxDE3‑yG；其中，D为Ti元素，E为O元素；ADE3为能够提高Bi0.5Na0.5TiO3的稳定性的改性剂通式，以得到具有准同型相界的(Bi0.5Na0.5)(1‑x)AxDE3；G为能够在所述准同型相界处引入的弛豫剂通式；x的取值范围为0.06≤x≤0.25，y的取值范围为0＜y≤0.18。由于Bi0.5Na0.5TiO3经过改性剂的改性后结构更加稳定了，并且还具有了准同型相界，使得可以通过在准同型相界中引入弛豫剂来提高材料的性能。
