METAL OXIDE AND PIEZOELECTRIC MATERIAL |
| 摘要 |
<P>PROBLEM TO BE SOLVED: To provide a piezoelectric material which includes a compound free of lead and alkali metal and has a good piezoelectric property. <P>SOLUTION: In the piezoelectric material having a good piezoelectric property, tungsten bronze structure oxides being free of lead and alkali metal and represented by A<SB>x</SB>B<SB>10</SB>O<SB>30</SB>and A'<SB>x'</SB>B'<SB>10</SB>O<SB>30</SB>are combined to form a morphotropic phase boundary. The A<SB>x</SB>B<SB>10</SB>O<SB>30</SB>is Ba<SB>4</SB>Bi<SB>2/3</SB>Nb<SB>10</SB>O<SB>30</SB>, and the A'<SB>x'</SB>B'<SB>10</SB>O<SB>30</SB>is Sr<SB>3</SB>Ba<SB>2</SB>Nb<SB>10</SB>O<SB>30</SB>. <P>COPYRIGHT: (C)2010,JPO&INPIT |
