Title: Electrode paste for laminated porcelain capacitor
Inventor: HORIBE YASUTAKA
IPC: H01G4/008
Filed: 1988-11-07
Abstract: PURPOSE:To obtain an electrode paste which has low resistivity and is manufactured at a low cost and further, prevents the formation of a diffusion layer between an internal electrode and a dielectric layer even after burning by making electrode paste of Ln1-XSrXCoO3 conductive oxide, Pd powder, organic binder, and organic solvent. CONSTITUTION:An internal electrode paste for a capacitor is composed of Ln1-XSrXCoO3 (Ln: lanthanoids) conductive oxide, Pd powder, organic binder, and organic solvent. As Ln1-XSrXCoO3 and BaTiO3 belong to the same oxides, they have very similar thermal properties in comparison with metals such as Pt and the like. Then, using this internal electrode paste, a laminated porcelain capacitor may suppress the development of delamination exceedingly in comparison with cases of conventional electrode pastes. If taking into consideration of aspects of a manufacturing cost and suppression of delamination, it is preferable to lessen the amount of Pd used and if taking into consideration of the aspects of suppression of the formation of diffusion layers and resistivity, it is desirable to increase the amount of Pd used. In view of the above circumstances, favorable results are obtained when compounding ratio between the conductive oxides and Pd powders is within its ranges 80/20-10/90.
