Abstract (en)

[origin: DE19814631A1] The purpose of the present invention is to prevent excessive variations, after application of a load, in the DC priming voltage Uag of gas-filled discharge gaps that include a vitreous-type electrode-activation mass comprising a plurality of components. To this end, the base components of the electrode-activation mass (4) include not only sodium silicate, cesium silicate and titanium, but also potassium silicate and cesium tungstate.
