Abstract

Protective coatings on the inner surfaces of discharge envelopes of radiation sources contain oxides of aluminum, yttrium, magnesium, zirconium, and thorium. Protective coatings make it possible to increase the inertness of glass burners on the inner surface of discharge envelopes with respect to vapors of corrosive metals at high temperatures and pressures as well as to increase several-fold the service life of mercury-cesium lamps with very small reduction of radiation during operation within the bounds of their required service life.
