Abstract
A process for making capacitors using electrode compositions of finely divided particles of noble metals and certain inorganic metal oxides dispersed in an inert organic medium. Suitable inorganic metal oxides are MoO.sub.3, GeO.sub.2, Pb.sub.5 Ge.sub.3 O.sub.11, Nb.sub.2 O.sub.5, NiO, ZnO, SnO.sub.2, CdO, metal phosphates, metal fluorides, phosphate glasses, germanate glasses, fluoride glasses and mixtures and precursors thereof.
Claims7
A metallization for the preparation of electrodes for monolithic capacitors which is a mixture of finely divided particles of (a) 70-99.5% by weight noble metal selected from the group consisting of silver, gold, palladium, platinum, and mixtures and alloys thereof, and (b) 30-0.5% by weight of an inorganic metal oxide selected from the group consisting of MoO.sub.3, GeO.sub.2, Pb.sub.5 Ge.sub.3 O.sub.11, Nb.sub.2 O.sub.5, ZnO, SnO.sub.2, CdO, metal phosphates, metal fluorides, phosphate glasses, germanate glasses, fluoride glasses, borosilicate glasses and mixtures and precursors thereof.
