摘要

INCREASING THE OXIDATION RESISTANCEOF MOLYBDENUM AND ITS USE FOR LAMP SEALSABSTRACTThe life of electric lamps exposed to anoxidizing environment at elevated temperature andhaving hermetic seals between molybdenum and avitreous material is substantially increased byapplying alkali metal silicate to the surface of thatportion of the molybdenum in the seal area which isexposed to said oxidizing environment.
