Abstract:
(EN) This piezoelectric material is lead-free, contains a perovskite-type metal oxide comprising Na, Nb, Ba, Ti, and Mg, and exhibits good piezoelectric properties. When the proportions by number of Na atoms, Nb atoms, Ba atoms, Ti atoms, and Mg atoms among Na, Nb, Ba, Ti, and Mg atoms contained in the piezoelectric material are represented by a, b, c, d, and e, respectively, the proportions a, b, c, d, e by number satisfy the following relational expressions: 0.430≤a≤0.460; 0.433≤b≤0.479; 0.040≤c≤0.070; 0.0125≤d≤0.0650; 0.0015≤e≤0.0092; 0.9×3e≤c-d≤1.1×3e; and a+b+c+d+e=1.
