Piezoelectric ceramics and multi-layered piezoelectric ceramic components |
| 摘要 |
A piezoelectric ceramic comprising as a main component an alkali-containing niobate-based perovskite structure expressed by a compositional formula (LixNayK1-x-y)a(Nb1-zTaz)O3 (provided: 0.04<x@0.1, 0@y@1, 0@z@0.4, and 0.95@a@1.005); wherein a crystal phase or an amorphous phase containing Si and K is made present at a grain boundary or a grain boundary triple point of a plurality of crystal grains constituting the piezoelectric ceramic. |
