Abstract
A method of coating the inside surface of the envelope of an electric incandescent lamp, containing a tungsten filament, with a gettering layer comprising one or more of the metals barium, calcium and strontium, comprises coating the filament with a compound having a composition defined by the formula MeO (XOp)q and heating in the evacuated lamp so that the free metal Me is liberated from the compound where Me is one or more of the metals barium, calcium and strontium, and X is one or more of the elements cerium, titanium, zirconium, hafnium, thorium, vanadium, niobium, tantalum, chromium, molybdenum, tungsten, manganese and rhenium. In the formula p is half the valency of element X and q is equal to or greater than 1. The coating is supplied to the filament by any suitable method such as dipping, coating, spraying or cataphoresis, the quantity applied being not more than 2% by weight of the filament so that the quantity of tungsten drawn from the filament during gettering is small.
