The invention discloses a bismuth sodium strontium zirconate doped potassium sodium niobate based piezoelectric ceramic material and a preparation method thereof. KNN)-based ceramic powder materials; then bismuth sodium strontium zirconate doped KNN-based ceramics were prepared by electronic ceramic preparation processes such as granulation and tableting, debinding, sintering, and silver testing. The piezoelectric and dielectric properties of KNN are greatly improved by the doping of the component Sr(BiNa)ZrO 3 , and the KNN has good temperature stability, which is expected to prepare piezoelectric devices. |
