【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.
