Tungsten – NutraWiki

Tungsten and its alloys are widely used for filaments in older style (not energy saving) electric bulbs and electronic tubes. Tungsten is also used as the filament in halogen tungsten lamps. These lamps use halogens like bromine and iodine to prevent the tungsten filament from degrading and are therefore more energy efficient than standard incandescent light bulbs.

By the end of the 19th century, tungsten salts were used to make coloured cotton fast or washable and to make clothes used for theatrical and other purposes non-inflammable. In the 1930''s, new applications arose in the oil industry for the hydrotreating of crude oils and, in the sixties, new catalysts were invented containing tungsten compounds to treat exhaust gases.
