誘電体磁器組成物、電子部品および複合電子部品
Document Type and Number:
Japanese Patent JP5786878
Kind Code:
B2
Abstract:
In order to provide a dielectric ceramic composition capable of sintering at a low temperature, implementing a low relative dielectric constant, providing other excellent properties (such as a relative density and an insulation resistance), performing co-firing of different materials, and suppressing dispersion of Ag in the sintered body when the internal electrode is formed, the dielectric ceramic composition includes a main ingredient containing SiO2—K2O—B2O3-based glass of 40 to 65 weight %, quartz of 35 to 50 weight %, and amorphous silica of remaining weight %; and a subsidiary ingredient containing alumina of 1.5 to 4 weight %, K2O-MO—SiO2—B2O3-based glass (where “MO” denotes at least any one selected from a group consisting of CaO and SrO) of 5 to 20 weight % relative to the main ingredient of 100 weight %.
