Abstract (en)
[origin: US2002008477A1] A method for producing an electric lamp having a vitreous lamp bulb and a foil of molybdenum or a doped molybdenum alloy which is pinched in the lamp bulb includes post-treating the unfinished foil such that substantially non-contiguous, insular regions of material agglomerates are formed. The material agglomerates are formed of molybdenum, molybdenum alloys, titanium, silicon, an oxide, a mixed oxide and/or an oxidic compound, with a vapor pressure of in each case less than 10 mbar at 2000° C. The substantially non-contiguous, insular regions are formed on at least 5 percent and at most 60 percent of the area of the foil surface. In this way, the adhesive strength between the foil and the glass and therefore also the service life of the lamp are significantly improved.
