PIEZOELECTRIC MATERIAL COMPOSITION, PRODUCTION METHOD THEREOF, PIEZOELECTRIC ELEMENT, AND DEVICE INCLUDING PIEZOELECTRIC ELEMENT
To enhance the piezoelectric property regardless of use of a lead-free piezoelectric material composition.SOLUTION: An piezoelectric element according to an embodiment thereof comprises: a piezoelectric element layer containing a first substance and a second substance surrounded by a layer of the first substance; a first electrode part disposed on a first face of the piezoelectric element layer; and a second electrode part disposed on a second face of the piezoelectric element layer opposed to the first face. The piezoelectric element layer contains a composition given by 0.96(NaaK1-a)(Nbb(T1-b))O3-(0.04-x)MZrO3-x(BicAg1-c)ZrO3+dmol%NaNbO3. (In the formula, T is Sb or Ta, M is Sr, Ba or Ca, 0.4≤a≤0.6, 0.90≤b≤0.98, 0.4≤c≤0.6, 0≤d≤5.0 and 0≤x≤0.04.)SELECTED DRAWING: Figure 2
【課題】鉛を含まない圧電材料組成物を用いながら圧電特性を向上させる。【解決手段】本明細書の実施例に係る圧電素子は、第１物質および第１物質層によって囲まれた第２物質を含む圧電素子層、圧電素子層の第１面に配置された第１電極部、および第１面に対向する圧電素子層の第２面に配置された第２電極部を含み、圧電素子層は、０．９６（ＮａａＫ１－ａ）（Ｎｂｂ（Ｔ１－ｂ））Ｏ３－（０．０４－ｘ）ＭＺｒＯ３－ｘ（ＢｉｃＡｇ１－ｃ）ＺｒＯ３＋ｄｍｏｌ％ＮａＮｂＯ３（式中、ＴはＳｂまたはＴａ、ＭはＳｒ、Ｂａ、またはＣａ、０．４≦ａ≦０．６、０．９０≦ｂ≦０．９８、０．４≦ｃ≦０．６、０≦ｄ≦５．０、０≦ｘ≦０．０４）の組成を含む。【選択図】図２
