| 简介 |
A multi-layer ceramic capacitor has a structure where its dielectric layers are constituted by a sintered compact that contains a mol of ReO3/2, b mol of SiO2, c mol of MOx, d mol of ZrO2, and e mol of MgO (where Re is a rare earth element, M is a metal element (except for Ba, Ti, Re, Si, Zr, Mg, and rare earth elements), and x is a valance) per 100 mol of BaTiO3, and a, b, c, d, and e mentioned above which indicate the mol numbers of respective constituents per 100 mol of BaTiO3 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, respectively.
Provide a multi-layer ceramic capacitor that allows for high-density layering and still achieves improved reliability by means of suppressing the grain growth when the dielectric grains constituting the dielectric layers are sintered and thereby ensuring sufficient grain boundary, while also setting a high dielectric constant per unit grain size.
