Abstract

The invention discloses a metal cream component applied to producing a capacitor, which serves as a terminal electrode of a capacitor. The metal cream component of the capacitor consists of metal powder, an organic adhesive, glass powder and a metal oxide such as bismuth oxide (Bi2O3), nickel oxide (NiO), zinc oxide (ZnO), boron oxide (B2O3), cuprous oxide (Cu2O), tin oxide (SnO2), manganese oxide (Mn2O3), MnO2 (manganese dioxide), aluminum sesquioxide (Al2O3), silicon dioxide (SiO2), zirconium dioxide (ZrO2) and copper oxide (CuO). The metal cream component of the capacitor of the invention is used for coating the two sides of a capacitor medium to form a thickness; after an appropriate producing process, the capacitor aiming at reducing cost, modifying electric property and protecting environment is produced.

Description

technical field [0001] The invention relates to a capacitor metal paste composition. Background technique [0002] The existing method for manufacturing disc or flat ceramic capacitors is to use an existing silver paste, including silver powder, inorganic binder and metal oxide, as a conductive paste in the atmosphere and burn it to the terminal electrodes. Silver is a kind of precious metal, which is expensive, which further increases the cost of the aforementioned capacitor products. Moreover, silver is easy to diffuse in ceramic components, and this feature of silver is likely to cause potential electrical abnormalities of the aforementioned capacitors. [0003] There are other existing methods in the current market, one of which is to focus on cost reduction, do not use the aforementioned existing silver glue, but use an existing copper glue on the aforementioned disc or flat ceramic capacitor as Conductive plastic. The existing copper glue includes fine copper powder,...
