Abstract
Current inrush limiter for incandescent lamps is made by mixing finely divided vanadium sesquioxide and vanadium pentoxide with finely divided glass-forming constituents which include vanadium compound. The mix is compacted and sintered in a substantially inert atmosphere which converts the vanadium oxides to vanadium dioxide maintained in a chemically stable and mechanically strong mass by vitreous binder.
