A molybdenum foil seal in silica glass which can be used, for example, for gas-tight electrical feedthroughs of lamp vessels. The ends 4c, bounded by cut edges 4b, of the molybdenum foil 4 sealed in the silica glass 1 are constructed according to the invention in the shape of a wedge. The wedge shape is produced by rolling the foil ends 4c. As a result, burrs on the cut edges 4b areeliminated, and the risk of the formation of cracks or flaws in the silica glass 1 is obviated.
Cette invention concerne une pellicule de molybdène scellée sous verre de silice et pouvant servir, par exemple, à assurer l'étanchéité au gaz des traversées d'alimentation d'ampoules électriques. Selon la présente invention, les bouts 4c de la pellicule de molybdène 4 scellée sous verre de silice 1, délimités par les rives découpées 4b, ont la forme d'un coin obtenue par roulage desdits bouts 4c. En conséquence, les rives découpées 4b sont exemptes de bavures, et les risques de formation de pailles dans le verre de silice 1 ou de fissuration sont éliminées.
