Abstract (en)
[origin: DE10038841C1] Silicon dioxide glass bulb has a current duct (1) made from a gas-tight composite material (1a) consisting of a precious metal having a melting point of more than 1700 deg C and silicon dioxide. The precious metal and the silicon dioxide are homogeneously distributed in the composite material. The precious metal is present in an amount of 10-50 vol.% and the silicon dioxide layer (1b) covers the composite material in the region of the connection with the glass bulb. An Independent claim is also included for a process for the production of a gas-tight connection between a silicon dioxide glass bulb and a current duct. Preferred Features: The precious metal is an alloy of ruthenium, rhenium and/or iridium.
