Abstract

Conducting surfaces are formed on resistances of sintered semi-conducting material, such as oxides of chromium, manganese, or uranium, by applying a paste containing the electrode metal before the resistance is sintered. The paste consists of glue, collodion, paraffin, &c. containing iron, cobalt, nickel, copper, silver, molybdenum, or tungsten in metallic form or as an easily reducible compound. The resistance may be partially sintered before applying the paste, after which the full sintering temperature is applied.
