Abstract
Abstract Metalizing compositions comprising alloys of three or more metals are used in ceramic capacitor electrodes and capacitors therefrom. The alloys have a critical surface area. The specific metals of the alloy are palladium, platinum and gold. The metalizing compositions are especially suitable for producing capacitors on ceramic dielectric substrates which contain bismuth stannate.
