A novel approach to reduce electrode costs in ceramic capacitors is presented. Barium metaplumbate (BaPbO 3 ) was fired onto sintered commercial (Ba, Sr)TiO 3 disk capacitors as external electrodes. Samples were compared to disk capacitors of the same composition with electrodes made of sputtered gold and air‐dried silver. The ceramic electrode led to substantial changes in the insulation resistance and dc breakdown strengths, but other properties remained the same. The feasibility of using BaPbO 3 electrodes strongly depends on chemical reactions between the electrode and dielectric.
