Piezoelectric material, method for producing piezoelectric material, piezoelectric device and liquid discharge device |
| 摘要 |
A piezoelectric material of the invention includes a perovskite oxide (P) (which may contain inevitable impurities) represented by the formula below: Pba(Zrx,Tiy,Mb-x-y)bOc  (P) (wherein M represents one or two or more metal elements; wherein 0<x<b, 0<y<b, 0≦̸b-x-y; and wherein a molar ratio a:b:c is 1:1:3 as a standard; however, the molar ratio may be varied from the standard molar ratio within a range where a perovskite structure is obtained). The perovskite oxide (P) has a signal intensity ratio I(Pb4+)/I(Pb2+) between Pb4+ and Pb2+ of more than 0 and less than 0.60 measured through XAFS. |
