摘要: 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 EDS analysis showed that presence would eliminate enormously Ag diffusion into dielectric layer, resulting a smooth dense interface contact less porous defects near electrode/dielectric region. property results indicated leakage current loss had decreased by about an order magnitude 20%, respectively. These explained weakened silver due to between paste/dielectric interface.
