What You Don't Know About The Applications of Sodium Tungstate
Sodium tungstate is a kind of tungstate, and its chemical formula is Na 2 WO 4 . The appearance is colorless crystalline or white crystalline powder, soluble in water, insoluble in ethanol, slightly soluble in liquid ammonia, when confront a strong acid it is broken down into tungstic acid dissolved in water. Sodium tungstate, as a raw material for chemical synthesis of tungsten, is an important intermediate in the transformation of tungsten into metals, usually, the intermediate product is broken down by alkaline process, and sodium tungstate is obtained, but in here sodium tungstate refers to crude sodium tungstate containing impurities. It also needs to be obtained by ion exchange, precipitation, extraction and other processes. Finally, APT is obtained by evaporation crystallization. Although sodium tungstate is an intermediate product of tungsten in the process of transformation, we use a lot of sodium tungstate, usually used in industrial products in tungstate refers to ...
