KNN-based leadless piezoelectric ceramic material
The invention relates to the field of electronic ceramic materials, in particular to a KNN-based lead-free piezoelectric ceramic material which comprises the following chemical components: (1-alpha) (KxNa1-x) (NbyTa1-y) O3-alphaMRAlO4 + sintering aid, alpha, x and y are atomic percent, and the sum of the atomic percent of the (1-alpha) (KxNa1-x) (NbyTa1-y) O3-alphaMRAlO4 + sintering aid is 100 percent. Alpha is in a range of 0.01 to 0.1; x ranges from 0.4 to 0.6; y is in the range of 0.85 to 0.99; m is a group IIA element; r is a rare earth element; the use amount of the sintering aid is 0.1-1% of the mass of the (1-alpha) (KxNa1-x) (NbyTa1-y) O3-alphaMRAlO4. The KNN-based leadless piezoelectric ceramic material prepared by the invention has excellent piezoelectric property and has great application potential in the field of piezoelectric ceramic sensors.
本发明涉及电子陶瓷材料领域，具体为一种KNN基无铅压电陶瓷材料，其化学组成如下：(1‑α)(KxNa1‑x)(NbyTa1‑y)O3‑αMRAlO4+烧结助剂，其中，α、x、y为原子百分比；α为0.01‑0.1；x为0.4‑0.6；y为0.85‑0.99；M为ⅡA族元素；R为稀土元素；烧结助剂的用量为(1‑α)(KxNa1‑x)(NbyTa1‑y)O3‑αMRAlO4质量的0.1‑1%，本发明所制备的KNN基无铅压电陶瓷材料具有优异的压电性能，在压电陶瓷传感器领域具有极大的应用潜力。
