ABSTRACT:
A composition consisting essentially of 60.0-70.0 mol % TiO.sub.2, 14.3-20.0 mol % Nd.sub.2 O.sub.3, 11.0-16.7 mol % BaO, 1.0-8.0 mol % ZrO.sub.2 and 0.05-0.30 mol % CeO.sub.2. This composition is useful for forming densified ceramic dielectric bodies having a dielectric constant of at least 65 and which meet COG specifications, and multilayer capacitors that contain such dielectric bodies.
