DIELECTRIC PORCELAIN COMPOSITION, ELECTRONIC DEVICE AND METHODS FOR PRODUCING THESE

摘要

A dielectric porcelain composition at least contains a main component including a dielectric oxide having a composition represented by the formula: [(CaxSr1-x)O]m[(TiyZr1-y-zHfz)O2], a first sub-component including an Mn oxide and/or an Al oxide, and a glass component. The symbols m, x, y, and z in the above formula expressing the composition molar ratio of dielectric oxide included in the main component are respectively within the following ranges: 0.90 <= m <= 1.04, preferably 1.005 <= m <= 1.025; 0.5 <= x < 1, preferably 0.6 <= x <= 0.9; 0.01 <= y <= 0.10 preferably, 0.02 <= y <= 0.07; 0 < z <= 0.20, preferably 0 < z <= 0.10.
