Tungsten applicatin - tungsten electric vacuum lighting materials

Tungsten is used as tungsten filament, tungsten band and various forging components form for vacuum tube production, radio electronics, and X-ray technology. Tungsten is the best material to manufacture the glower and spiral wire. High working temperature (2200 to 2500 ° C) can ensure a high luminous efficiency, and the small rate of evaporation can ensure the long life of the filaments. Tungsten can be used for manufacturing the directly heated cathode and the grid electrode in electronic shock tubes, the cathode of the high-voltage rectifier and the indirectly heated cathode heater in a variety of electronic equipments. Tungsten can be used for the manufacture of X-ray tubes and the cathode and anticathode of gas radiation tubes, and the radio device contacts and atomic hydrogen torch electrode. Tungsten and tungsten rod can be used as a high-temperature furnace (3000 ℃) heater. Tungsten heater should work in hydrogen atmosphere, inert atmosphere or vacuum.
