Method of producing piezoelectric ceramic device |
| abstract |
Material of piezoelectric ceramic compound of three components of Pb(Zn1/3Nb2/3)O3-PbTiO3-PbZrO3 expressed by a basic formula of Pb(Zn1/3Nb2/3)aZrTixO3 (where 0.90<a+x+y<1.00) is provided. The material is calcined. The calcined material is milled to provide powder. A formed body containing the powder is provided. The formed body is degreased at a temperature having the formed body not sintered. A sintered body is provided by sintering the degreased body. The sintered body is heated to subject the sintered body to predetermined heat treatment. The sintered body subjected to the predetermined heat treatment is polarized to provide the sintered body with a piezoelectric property, thus providing a piezoelectric ceramic device. This piezoelectric ceramic composition can be sintered together with an electrode consisting mainly of Ag at a low temperature. Even after the sintering, the composition has its insulation resistance not decrease and has its piezoelectric properties not decline. The piezoelectric ceramic composition has its insulation resistance not decrease even in high-temperature and high-humidity condition, thus having stable characteristics. |
