Claim 1
Independent Claim
116 words
THE METHOD OF MAKING AN ELECTRIC CAPACITOR WHICH COMPRISES PROVIDING A SLURRY CONSISTING OF CERAMIC MATERIAL HAVING A DIELECTRIC CONSTANT OF GREATER THAN 200, IN A VEHICLE WHICH CAN BE EVAPORATED WITHOUT LEAVING A RESIDUE, PROVIDING A METALLIC CAPACITOR ELECTRODE CAPABLE OF SUPPORTING SAID SLURRY AND WHICH IS NONOXIDIZABLE IN AIR AT TEMPERATURES UP TO AN INCLUDING THE TEMPERATURE AT WHICH SAID CERAMIC MATERIAL VITRIFIES, APPLYING A COATING OF SAID SLURRY TO SAID ELECTRODE, HEATING SAID COATING IN SITU TO EVAPORATE SAID VEHICLE THEREFROM, VITRIFYING THE CERAMIC MATERIAL OF SAID COATING ON SAID ELECTRODE, AND APPLYING A COATING OF METAL OVER THE VITRIFIED CERAMIC MATERIAL ON SAID ELECTRODE TO FORM A SECOND ELECTRODE FOR THE CAPACITOR.
