Abstract
A ceramic dielectric includes a plurality of semi-conductive grains including a semiconductor oxide including barium (Ba), titanium (Ti), and a rare earth element. A ceramic dielectric also includes an insulative oxide located between adjacent semiconductor grains and an acceptor element including manganese (Mn), magnesium (Mg), aluminum (Al), iron (Fe), scandium (Sc), gallium (Ga), or a combination thereof, a method of manufacturing the ceramic dielectric, and a ceramic electronic component, and an electronic device including the ceramic dielectric.
