Study of the brazing physicochemical processes of structural elements of the gas discharge lamps with sapphire shell

ABSTRACT

In the present work, the results of the research gas discharge lamp constructive elements those made from niobium and zirconium alloy, sealing by means of melting titanium with its alloy with nickel are presented. It is performed construction peculiarities analysis of gas discharge lamp with sapphire shell. The requirements to sealing materials are formed. It is studied physical and chemical processes occurring in materials during lamp sealing and lifetime.
