Electrode activating compound for gas discharge tube

摘要

An electrode activating compound for a gas discharge tube such as a surge voltage arrester, triggerable gas discharge tubes and flash tubes in which a titanium oxide is used in place of the radioactive thorium oxide. Preferably, the titanium oxide is provided by a reduction of a titanium dioxide with a reducing agent such as BaAl4 or metallic titanium or by oxidation of a titanium hydride in either an oxidizing atmosphere or with an oxidizing compound.
