Dielectric ceramic composition, electronic device, and multilayer ceramic capacitor

摘要

A dielectric ceramic composition including dielectric particles and grain boundary phases present among these dielectric particles, wherein when measuring a concentration of Si and/or element "A" contained in the grain boundary phases (where, "A" is at least one element selected from cationic elements with an effective ion radius in sixfold coordination of 0.065 nm to 0.085 nm), the concentration of the Si and/or element "A" disperses depending on the position in the grain boundary phases, and the dispersion of the concentration of Si and/or element "'A" in the grain boundary phases is, in terms of CV value, larger than 10% and less than 58%. According to the present invention, a dielectric ceramic composition and an electronic device excellent in capacity-temperature characteristic while realizing a good high temperature accelerated life can be realized.
