DEACTIVATION METHOD OF USED MERCURY-CONTAINING LUMINESCENT LAMPS Russian patent published in 2013 - IPC C22B43/00 B09B3/00 

FIELD: metallurgy.

SUBSTANCE: method involves connection of an inner volume of a lamp and a reservoir volume to a demercurisator so that contact of mercury vapours to the demercurisator is provided and the demercurisation process is performed in the lamp volume. The reservoir with the demercurisator is arranged in a lamp base. Demercurisation process is performed in a single tight volume formed with inner volumes of the lamp and the reservoir with the demercurisator through a connection of volumes of the lamp and the reservoir to the demercurisator by destructing a partition wall from low-melting material, which separates them, and by increasing pressure in the reservoir with the demercurisator.

EFFECT: providing possibility of utilisation of the lamp in situ after its failure; increasing safety and simplifying utilisation of lamps.
