Title:
ELECTRICALLY CONDUCTIVE OXIDE SINTERED COMPACT, MEMBER FOR ELECTRICAL CONDUCTION, GAS SENSOR, PIEZOELECTRIC ELEMENT, AND METHOD FOR PRODUCING PIEZOELECTRIC ELEMENT
Document Type and Number:
WIPO Patent Application WO/2016/098309
Kind Code:
A1
Abstract:
In the present invention, an electrically conductive oxide sintered compact contains a crystal phase having a perovskite type oxide crystal structure represented by the compositional formula REaCobCucNidOx (here, RE denotes a rare earth element, a+b+c+d = 1, and 1.25 ≤ x ≤ 1.75). The coefficients a, b, c and d satisfy the relationships 0.474 ≤ a ≤ 0.512, 0.050 ≤ b ≤ 0.350, 0 < c < 0.250 and 0.050 ≤ d ≤ 0.350.
