METHOD FOR PRODUCING SEMICONDUCTOR CERAMIC COMPOSITION

SHIMADA TAKESHI / UEDA ITARU / INO KENTARO

Provided is a semiconductor ceramic composition that is a lead-free semiconductor ceramic composition in which a portion of Ba in a oxide is substituted by Bi and A (in which A is at least one kind of Na, Li and K), the semiconductor ceramic composition having a region between a center portion and an outer shell portion within a crystal grain, in which when Bi concentration is measured in a radial direction within the crystal grain, the Bi concentration in the region is higher than both Bi concentration in the center portion and Bi concentration in the outer shell portion.
