Abstract: A ceramic discharge vessel (8) for a high-pressure discharge lamp has a pin-like feedthrough (10) inserted in a plug (11) made from a composite material. The feedthrough (10) has been sintered directly into the plug (11) and is additionally sealed by covering the area, surrounding the feedthrough, of the plug's surface facing away from the discharge volume with a ceramic sealing material (7a).

Abstract: The invention provides a method for producing a polycrystalline transparent sintered alumina body suitable for use in a ceramic envelope for a high intensity discharge lamp, with optimized kinds and amounts of sintering aids. First, adding and mixing, to alumina of a purity of 99.9 % or higher, MgO within a range from 0.002 to 0.010 wt.% and La 2 O 3 within a range from 0.005 to 0.020 wt.%, in such a manner that a sum of MgO and La 2 O 3 is 0.030 wt.% or less and that a ratio thereof satisfies a relation 0.2¤MgO/La 2 O 3 ¤0.5. Next, firing a mixture at 900 to 1200°C and cast molding the fired alumina. Then, after a chelating treatment, sintering the molded alumina for at least 1 hour at 1650 to 1900°C in a reducing atmosphere under a normal pressure.
