Potassium-sodium niobate-based leadless piezoelectric ceramic and preparation method thereof
The invention relates to a potassium sodium niobate-based leadless piezoelectric ceramic and a preparation method thereof, the chemical general formula of the potassium sodium niobate-based leadless piezoelectric ceramic is 0.965 K < 0.45 > Na < 0.55 > Nb (1-x) TaxO < 3 >-0.035 Bi < 0.5 > (Na < 0.82 > K < 0.18 >) < 0.5 > ZrO < 3 >-0.8%, CuO < 0.2 >%, CuF < 2 >-0.3% Fe2O3, and x is greater than 0 and less than or equal to 0.04. The potassium-sodium niobate-based leadless piezoelectric ceramic does not contain a lead element, belongs to an environment-friendly material, has a relatively high mechanical quality factor, a good piezoelectric constant and relatively low dielectric loss, and has a wide application range. Finally, the preparation method is simple and stable in process, easy to operate and convenient for industrial production.
