Niobium hafnium zirconium potassium sodium lithium bismuth copper lead-free piezoelectric ceramic material and preparation method thereof, and lead-free piezoelectric ceramic and preparation method thereof
The invention discloses a niobium hafnium zirconium potassium sodium lithium bismuth copper leadless piezoelectric ceramic material and a preparation method thereof, and a leadless piezoelectric ceramic and a preparation method thereof, the chemical general formula of the niobium hafnium zirconium potassium sodium lithium bismuth copper leadless piezoelectric ceramic material is [(K < 0.45 > Na < 0.55 >) < 0.955 > (1-y) Li < 0.955 > y (Bi < 0.5 > Na < 0.5 >) < 0.045 > Cu < 0.01 >] [Nb < 0.955 > (Hf < 1-x > Zrx) < 0.045 > Fe < 0.005 >] O3, 0 < x < = 0.4, and 0 < = y < = 0.04. The niobium hafnium zirconium potassium sodium lithium bismuth copper lead-free piezoelectric ceramic obtained by the preparation method disclosed by the invention has relatively high piezoelectric activity and also keeps a relatively high mechanical quality factor; and the Curie temperature can be effectively increased while the high piezoelectric property is achieved, and the material can be applied in a larger temperature range.
