Multilayer ceramic chip capacitors which satisfy X7R and BX requirements
and which are compatible with silver-palladium internal electrodes are
made in accordance with the invention. The capacitors exhibit desirable
dielectric properties (high capacitance, low dissipation factor, high
insulation resistance), excellent performance on highly accelerated life
testing, and very good resistance to dielectric breakdown. The dielectric
layers comprise a lead-free and cadmium-free barium titanate base
material doped with other metal oxides such oxides of zinc, boron,
bismuth, cerium, tungsten, copper, manganese, neodymium, niobium, silver,
barium, silicon and nickel in various combinations. The dielectric
ceramic materials herein can be sintered together (fired) at less than
1000.degree. C. with an inner electrode having more than 80 wt % Ag and
less than 20 wt % Pd to form a multilayer ceramic capacitor (MLCC).
