【chinatungsten】Tungsten Applications in Lighting Industry

About 4-5% of annual worldwide tungsten production is consumed by the lighting industry. The largest market is still for incandescent lamps. However, more than 70% of artificial lighting is today generated by fluorescent lamps and this portion is steadily increasing. Modern production units can produce more than 6000 lamps per hour. Tungsten is used in the forms of wires, coils, and coiled coils in incandescent lamps, and as electrode in low-and high-pressure discharge lamps.

【Chinatungsten】Production-process-of-thorium-tungsten-electrode

The first step to produce thorium tungsten electrode is to dope thorium nitrate into ammonium paratungstate, which is shorted to APT. After roasting, doped APT becomes doped BTO, blue tungsten oxide. After that, reduce blue tungsten oxide to tungsten powder.
Raw material used to produce blue tungsten oxide is APT, shorted from ammonium paratungstate. It is a kind of white crystal, can be slightly soluble in water.
