| titleOfInvention | Method of manufacturing oxide piezoelectric element |
| abstract | As the piezoelectric element of oxide is expanded to the application range of gas range, gas lighter, ignition element, ultrasonic cleaner, and electric and electronic parts, oxide piezoelectric material with excellent electrical characteristics such as dielectric constant, piezoelectric constant, and electromechanical coupling coefficient is required. It became. In particular, since oxide piezoelectric elements have been applied to piezoelectric motors, high oxide piezoelectric materials capable of dielectric constants, piezoelectric constants, and electromechanical coupling coefficients have been required. Accordingly, development of oxide piezoelectric materials using additives has been attempted to improve electrical properties of oxide piezoelectric materials.n n n Conventionally, an oxide piezoelectric material using Na 2 CO 3 and Y 2 O 3 as an additive in Pb ((ZrO. 52 TiO. 48 ) 0.98 NbO. 2 ) O 3 system has been used to enhance the electrical properties as described above. In general, appropriate adjustment than the mixing and dispersion of the additive to be used may be produced oxide piezoelectric material having excellent electrical characteristics than the object of the present invention is Pb (with a Na 2 CO 3 and Y 2 O 3 as an additive ( ZrO. 52 TiO. 48 ) 0.98 NbO. 2 ) O 3 -based oxide piezoelectric material, Y (NO 3 ) 3 ยท 5H 2 which can enhance dispersibility when mixed instead of Y 2 O 3 oxide powder in additives By using O, an oxide piezoelectric element with improved electrical properties is provided. |
