Title:
Piezo-electric porcelain constituent
Document Type and Number:
Japanese Patent JP6039762
Kind Code:
B2
Abstract:
A piezoelectric device has a piezoelectric ceramic layer obtained by sintering a piezoelectric ceramic composition that contains an alkali-containing niobate type perovskite composition which is represented by (LilNamK1-l-m)n(Nb1-oTao)O3 (wherein 0.04≦l≦0.1, 0≦m≦1, 0.95≦n≦1.05, 0≦o≦1) and Ag component, as well as a conductor layer sandwiching the piezoelectric ceramic layer. The piezoelectric ceramic layer has Ag segregated in voids present in a sintered compact of the perovskite composition in terms of oxides relative to the perovskite composition.
