Title:
LAMINATED CERAMIC CAPACITOR AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2014/097678
Kind Code:
A1
Abstract:
Provided are a laminated ceramic capacitor capable of having a high dielectric constant while maintaining favorable temperature properties and the like, and a method for producing the same. The laminate of this laminated ceramic capacitor contains a perovskite compound containing Ba and Ti, contains one or more elements selected from a group consisting of Gd, Tb and Dy, and optionally contains an element selected from a group consisting of Y, Si, Mn, Mg and Zr. If the total amount of Ti contained therein is 100 molar parts, the amount (a) of the one or more elements selected from a group consisting of Gd, Tb and Dy is 0.2≤a≤0.8, the amount (b) of Y is 0.0≤b≤0.5, the amount (c) of Si is 0.0≤c≤2.5, the amount (d) of Mn is 0.0≤d≤0.25, the amount (e) of Mg is 0.0≤e≤1.2, the amount (f) of Zr is 0.0≤f≤0.5, and the molar ratio (m) of Ba amount/(Zr amount + Ti amount) is 0.99≤m≤1.01.
