PIEZOELECTRIC MATERIAL, PIEZOELECTRIC ELEMENT, AND ELECTRONIC APPARATUS |
| 摘要 |
The present invention provides a piezoelectric material not containing lead and potassium, having a high relative density, a high Curie temperature, and a high mechanical quality factor, and exhibiting good piezoelectricity. The piezoelectric material contains 0.04 percent by mole or more and 2.00 percent by mole or less of Cu relative to 1 mol of metal oxide represented by General formula (1) below.;((Na1-zLiz)xBa1-y)(NbyTi1-y)O3(in Formula, 0.70≦x≦0.99, 0.75≦y≦0.99, and 0<z<0.15) General formula (1) |
