ABSTRACT:
A composite body consisting of two or more formed parts of densely sintered aluminum oxide and a metal such as an envelope for a mercury vapor discharge lamp with a metal halide filling. The parts are connected together with material which comprises at least two of the oxides SiO.sub.2, Al.sub.2 O.sub.3 and B.sub.2 O.sub.3 and at least one of the trivalent oxides La.sub.2 O.sub.3 and Y.sub.2 O.sub.3. This material is applied at a relatively low temperature and is resistant to the gas filling up to approximately 1350.degree. C.
