Abstract: In manufacturing a vacuum-tight electric leadthrough in an electric discharge tube, a plug of indium or an indium alloy is provided in the leadthrough hole the wall of which is covered with a thin layer of nickel. During degassing which is carried out at a high temperature, the indium or the indium alloy melts, dissolves, the thin layer of nickel and then adheres rigidly to the released clean surface. This method is particularly suitable for use in leadthroughs for wall electrodes, as they occur in cathode-ray tubes and television camera tubes, in particular camera tubes of the vidicon type. It is then possible to obtain in one operation cycle the wall electrodes and the electric leadthroughs necessary for that purpose, as a result of which comparatively complicated systems can be manufactured in a rapid and cheap manner.
