HIGH DIELECTRIC CONSTANT TYPE CERAMIC COMPOSITION

摘要

When a portion of the Pb of a Pb(Zn1/3Nb2/3)O3based ceramic composition within the region bounded by lines connecting a, b, c and d points in the ternary composition diagram of the accompanying FIG. 1 is substituted by a small amount of Ba and/or Sr, a high dielectric constant type ceramic composition which has a small temperature coefficient of dielectric constant and which is effective as a material for multilayer ceramic capacitors is obtained.
