"ITatriumdanpfentladungslampe. ""I Sodium Vapor Discharge Lamp."

Die Erfindung bezieht si oh auf eine Oat ladung lampe, in der ITatriumdampf mit verhältnismäsaig hohem Druok im Betrieb verwendet wird. The invention relates to an Oat charge lamp, in which sodium vapor with a relatively high pressure is used in operation.

Eine Umhüllung, die für diesen "bekannten Lampentyp verwendet wird, besteht aua diohtgesintortem Aluminiumoxid, während die Entladungalampe mit Hiobiuminotall abgedichtet lot. Dieses Metall ist auf Grund seines Ausdehnungskoeffizienten (80 χ 10 ') , der ungefähr dem des dlohtgesinterten Aluminiumoxids gleich ist, sowie auf Qrund des hohen Sohmelzpunktea und wegen der Tatnaohe, dass es bis oa. 1000 C gegen die Einwirkung duroh Natriumdampf beständig ist, gewählt worden.An envelope that is used for this "known type of lamp is made of dioht-sintered aluminum oxide, while the discharge lamp is sealed with hiobium-aluminum. This metal is due to its expansion coefficient (80 χ 10 '), which is approximately the same as that of the dloht-sintered aluminum oxide." It was chosen because of the high melting point and the fact that it is resistant to the effects of sodium vapor up to 1000 C above.

Da diohtgosintertea Aluminiumoxid kein Sohmelzintervall aufweist, muse bei der Herstellung der Vorbindung des lliobiuma ein glasartiges Dichtungsmaterial verwendet werden. Diohtgeointertee Aluminiumoxid iat vorzugsweise polykriatallines Material mit hoher Röntgen-Because diohtgosintertea aluminum oxide has no Sohmelzintervall has, muse in the production of the pre-binding of the lliobiuma vitreous sealing material can be used. Diohtgeointertee alumina iat preferably polycrystalline material with a high X-ray

Es stellt sich Jedoch heraus, dass eine gute vakuumdichte Haftung nicht ohne weiteres erhalten werden kann. Dazu ist nämlich eine Vorbehandlung des lliobiums erfordern oh, die beispielsweise aus der Erhitzung im Vakuum des ITiobiums zusammen mit einem Gemisch aua ¥0« und Cr2O. besteht.However, it turns out that good vacuum-tight adhesion cannot be easily obtained.
