ELECTRICALLY CONDUCTIVE OXIDE SINTERED COMPACT, MEMBER FOR ELECTRICAL CONDUCTION, GAS SENSOR, PIEZOELECTRIC ELEMENT, AND METHOD FOR PRODUCING PIEZOELECTRIC ELEMENT
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.
La présente invention concerne un compact fritté d'oxyde électriquement conducteur contenant une phase cristalline ayant une structure cristalline d'oxyde de type pérovskite, l'oxyde étant représenté par la formule compositionnelle REaCobCucNidOx, dans laquelle RE représente un élément des terres rares, a + b + c + d = 1 et 1,25 ≤ x ≤ 1,75. Les coefficients a, b, c et d satisfont les relations 0,474 ≤ a ≤ 0,512, 0,050 ≤ b ≤ 0,350, 0 < c < 0,250 et 0,050 ≤ d ≤ 0,350.
