A metal halide lamp includes a ceramic discharge vessel and two electrodes. The discharge vessel encloses a discharge volume containing an ionizable gas filling including at least a metal halide, two current lead-through conductors connected to the respective electrode, and a seal having sealing material through which at least one of the respective current lead-through conductors issues to the exterior of the discharge vessel. The sealing material of the seal includes a ceramic sealing material with cerium oxide, aluminum oxide and silicon dioxide as a mixture of oxides and/or one or more mixed oxides. |
