CERAMIC, PIEZOELECTRIC DEVICE, AND PRODUCTION METHOD THEREOF |
摘要 |
To provide a piezoelectric ceramic containing BiFeO3 having a {110} plane orientation in a pseudo-cubic form, which is suited for the domain engineering, the piezoelectric ceramic includes a perovskite-type metal oxide represented by the following general formula (1), and has a {110} plane orientation in a pseudo-cubic form: xBiFeO3-(1-x)ABO3General Formula (1) where A and B each represent one kind or more of metal ions; A represents a metal ion having a valence of 1, 2 or 3; and B represents a metal ion having a valence of 3, 4, or 5, provided that x is within a range of 0.3@x@1. |
