99.5% Tungstic Acid 103

99.5% tungstic acid may be prepared by “dissociation-slurrying-acid decomposition” process. This process uses less raw materials and auxiliary materials. And it is easy to operate. So, it is cost-saving and time-saving. Some people have conducted experiments on acid decomposition of…

Product
Fe-doped Tungstic Acid 77

Fe-doped tungstic acid may be prepared using sodium tungstate and iron salts as materials. Since Fe initiates the Fenton reaction, the photocatalytic activity of tungstic acid is greatly improved. Also, this is a heterogeneous reaction that avoids the loss of…

Product
High-purity Tungstic Acid 70

High-purity tungstic acid is a new chemical material with a wide range of application prospects, which may be prepared by a new process of dissociation – slurrying – acid decomposition, with purity higher than 99.99% and average particle size of…

Product
Nano Grain Size Tungstic Acid 76

Nano grain size tungstic acid may be synthesized by chemical precipitation method using ammonium metatungstate (AMT) and hydrochloric acid (HCL) as raw materials, and the agglomeration of nanoparticles may be effectively improved with the addition of ethanol. And nano tungstic…

Yellow Tungstic Acid 145

Yellow tungstic acid is the most common seen tungstic acid that appears as a kind of light yellow powder or crystalline with a melting point of 1473°C. It can not easily dissolve in phosphorus acid when it is fresh produced.…

Product
White Tungstic Acid 129

White tungstic acid is one of different types of tungstic acid, showing the appearance of white crystalline powder. It is less active than microcrystalline structure white tungstic acid. However, it is active, optical sensitive and can be easy reduced. Its…

Product
Tungstic Acid 120

Tungstic acid is a kind of yellow powder with the relative density of 5.5. It refers to hydrated forms of tungsten trioxide (WO3). The simplest form, the monohydrate, is WO3•H2O, the dihydrate WO3•2H2O is also known. Its boiling point is…

Product
