PIEZOELECTRIC MATERIAL, PIEZOELECTRIC ELEMENT, AND ELECTRONIC EQUIPMENT |
| 摘要 |
There is provided a lead- and potassium-free piezoelectric material having a high piezoelectric constant and a satisfactory insulation property and a piezoelectric element that includes the piezoelectric material. The piezoelectric material contains a perovskite-type metal oxide having the general formula (1): (NaxBa1-y) (NbyTi1-y)O3 (wherein x satisfies 0.80≦x≦0.95, and y satisfies 0.85≦y≦0.95) and Zn, wherein the Zn content corresponds to more than 0 mol % and 5 mol % or less of the amount of perovskite-type metal oxide. The piezoelectric element includes the piezoelectric material. |
