Title:
MANUFACTURING METHOD OF PIEZOELECTRIC MATERIAL AND LAMINATED PIEZOELECTRIC ELEMENT
Document Type and Number:
Japanese Patent JP2006265059
Kind Code:
A
Abstract:

To provide a manufacturing method of a piezoelectric material and a laminated piezoelectric element which can be fired at a low temperature and can exhibit an excellent displacement amount even if fired at a low temperature.

The piezoelectric material contains 0.07 mol% or less of Sb2O3 or Sb2O5 against 1 mol of a compound expressed by general formula (1): (Pb1-xMax)(Zr1-y-zTiySbz)1-p-q(Y1/2Nb1/2)p(Mn1-B1-B2WB1SbB2)qO3 (wherein Ma is one kind or more selected from the group consisting of Ba, La, Sr, and Ce). In a manufacturing method of a laminated piezoelectric element 1 which is obtained by laminating piezoelectric layer 11 and internal electrodes layers 21, 22 alternately, as a piezoelectric material there is used a material containing a compound of above general formula (1) and Sb2O3 and/or Sb2O5.
