Piezoelectric film, ink jet head, method of forming image by the ink jet head, angular velocity sensor, method of measuring angular velocity by the angular velocity sensor, piezoelectric generating element, and method of generating electric power using the piezoelectric generating element
Abstract:
The present invention provides a non-lead piezoelectric film having high crystalline orientation, the low dielectric loss, the high polarization-disappear temperature, the high piezoelectric constant, and the high linearity between an applied electric field and an amount of displacement. The present invention is a piezoelectric film comprising: a NaxLa1-x+yNi1-yO3-x layer having only an (001) orientation and a (1-α) (Bi, Na, Ba) TiO3-αBiQO3 layer having only an (001) orientation. The (1-α) (Bi, Na, Ba) TiO3-αBiQO3 layer is formed on the NaxLa1-x+yNi1-yO3-x layer. The character of Q represents Fe, Co, Zn0.5Ti0.5, or Mg0.5Ti0.5 The character of x represents a value of not less than 0.01 and not more than 0.05. The character of y represents a value of not less than 0.05 and not more than 0.20. The character of α represents a value of not less than 0.20 and not more than 0.50.
Abstract(Chinese):

本发明提供一种具有高结晶取向，低介电损耗，高偏振消失温度，高压电常数以及施加电场与位移量之间的高线性度的非铅压电薄膜。 本发明是一种压电薄膜，它包括仅具有（001）取向的NaxLa1-x + yNi1-yO3-x层和仅具有（001）取向的（001）取向的（001）取向和（1-α）（Bi，Na，Ba）TiO3-αBiQO3层 ）方向。 在NaxLa1-x + yNi1-yO3-x层上形成（1-α）（Bi，Na，Ba）TiO3-αBiQO3层。 Q的特性表示Fe，Co，Zn0.5Ti0.5或Mg0.5Ti0.5 x的特征值不小于0.01且不大于0.05。 y的特征表示不小于0.05且不大于0.20的值。 α的字符表示不小于0.20且不大于0.50的值。
