Abstract
The present invention relates to a strip-like current feeder based on molybdenum-yttrium oxide, for electric lamps with a metal/glass sealing. In addition to molybdenum-yttrium oxide, the strip material contains 0.03 to 1.0% by weight cerium oxide and the ratio of cerium oxide to yttrium oxide amounts to 0.1 to 1. As compared to known current feeders, the current feeder according to the present invention has a distinctly enhanced resistance to corrosion or oxidation.
