Claim 1
Independent Claim
124 words
In a method of making a multielectrode ceramic capacitor by providing a green ceramic body containing a plurality of embedded electrodes, coating end portions of the green ceramic body with a paste containing finely divided metal particles and co-firing the green ceramic body and paste coating, the improvement which comprises employing as said paste a paste consisting essentially of a mixture, in an inorganic vehicle, of a finely divided metal selected from nickel and copper; glass frit, said glass being selected from barium borosilicate glass and barium aluminosilicate glass; and MnO 2 ; the properties by weight of the said metal, glass frit and MnO 2 being from about 80 to 95% metal 3 to 14% glass frit 1.5 to 3% MnO 2 .
