Abstract

Article dont l'agent de scellement a un coefficient de dilatation thermique proche de celui de la céramique d'alumine. Il comprend un corps de céramique et alumine 21 lié à une pièce de céramique ou de métal réfractaire 3 au moyen d'un agent de scellement 4 comprenant essentiellement, en poids : CaO 32 à 42 % BaO 10 à 19 % MgO jusqu'à 1 % Al2 O3 le complément à 100 % Application à la fabrication des lampes à vapeurs métalliques.Article whose sealant has a coefficient of thermal expansion close to that of alumina ceramic. It comprises a body of ceramic and alumina 21 bonded to a piece of ceramic or refractory metal 3 by means of a sealing agent 4 comprising essentially, by weight: CaO 32 at 42% BaO 10 at 19% MgO up to 1 % Al2 O3 the complement to 100% Application to the manufacture of metal vapor lamps.
