COATED CERAMIC DISCHARGE VESSEL FOR IMPROVED GAS TIGHTNESS

摘要

The present invention relates to a discharge vessel (1) with at least one end part (2) and a discharge cavity (3), whereby the discharge vessel (1) is at least partly coated with a coating layer (4), and whereby the gas-tight bonding of the coating layer to the discharge vessel (1), to a sealant (5) and/or to an end closure member (9) is stronger compared to the direct gas-tight bonding of said sealant (5) to said end closure member (9) and/or discharge vessel (1).
