PIEZOELECTRIC SINGLE CRYSTAL MATERIAL |
| 摘要 |
PROBLEM TO BE SOLVED: To provide a piezoelectric single crystal material which has a large electromechanical coupling coefficient and is low in the acoustic velocity. SOLUTION: The piezoelectric single crystal material has a composition expressed by chemical formula: (K<SB>3</SB>Li<SB>2</SB>)<SB>1-x</SB>Na<SB>x</SB>Nb<SB>5</SB>O<SB>15</SB>(wherein, 0≤X≤0.2) in which potassium and lithium constituting potassium lithium niobate are substituted with sodium.
