Title:
DROPLET EJECTION HEAD
Document Type and Number:
WIPO Patent Application WO/2008/029574
Kind Code:
A1
Abstract:
Disclosed is a droplet ejection head comprising a piezoelectric actuator using a piezoelectric porcelain composition containing no lead and having low temperature dependence of piezoelectric constant. Specifically disclosed is a droplet ejection head characterized by comprising a piezoelectric actuator using a piezoelectric porcelain composition containing a solid solution of a main component represented by the general formula (I) below and a sub-component represented by the general formula (II) below which is added in an amount of less than 1 mol% relative to the total amount of the solid solution. General formula (I): {LiX(K1-YNaY)1-X}(Nb1-Z-WTaZSbW)O3 (wherein 0 ≤ x ≤ 0.2, 0 ≤ y ≤ 1, 0 < z ≤ 0.4, and 0 < w ≤ 0.2) General formula (II): ABO3 (wherein A represents Bi, and B represents at least one of Fe, In and Sc)
