Title:
LAMINATED CERAMIC CAPACITOR
Document Type and Number:
WIPO Patent Application WO/2013/145421
Kind Code:
A1
Abstract:
By suppressing grain growth, which occurs when dielectric particles constituting a dielectric layer are fired to maintain grain boundaries, and by setting permittivity per unit grain size to a high value, high density laminated layers and improved reliability are both achieved in this laminated ceramic capacitor. The laminated ceramic capacitor has a dielectric layer constituting a sintered body containing, with respect to 100 moles of BaTiO3, amols of ReO3/2, bmols of SiO2, cmols of MOx, dmols of ZrO2, and emols of MgO (where Re is a rare earth element, M is a metal element (excluding Ba, Ti, Re, Si, Zr, Mg and rare earth elements), and x is a valence). The aforementioned a, b, c, d and e, which represent the number of moles of each component, are 0.1 ≤ a ≤ 1.0, 0.1 ≤ b ≤ 1.5, 0.1 ≤ c ≤ 0.4, 0 ≤ d ≤ 1.0, and 0 ≤ e ≤ 0.03.
