The electrical properties and microstructure of Na2O−PbO−Nb2O5−SiO2 glass-ceramic capacitors with pre-sputtered gold film as the transition layer in electrode design were investigated. SEM observation and EDS analysis showed that the presence of gold transition layer would eliminate enormously the Ag diffusion into the dielectric layer, resulting in a smooth and dense interface contact with less porous defects near the electrode/dielectric layer region. The electrical property results indicated that the leakage current and dielectric loss had decreased by about an order of magnitude and 20%, respectively. These results were explained by the weakened diffusion of silver into dielectric layer due to the presence of gold transition layer in between the silver paste/dielectric interface.
