Chemical reagent Ammonium tungstate
Ammonium tungstate is a chemical substance whose molecular formula is (NH4)10W12O41~xH2O. Mainly used to manufacture tungsten trioxide or blue tungsten oxide metal tungsten powder; the downstream products of metal tungsten powder include tungsten material series, such as tungsten bars, tungsten wire and other electric...
99.5% high purity ammonium tungstate
Uses: It can be used to make ammonium tungsten phosphate, etc. Raw material for the manufacture of ammonium phosphotungstate and other tungsten compounds. Metal tungsten and catalysts can also be produced.
Mainly used to manufacture tungsten trioxide or blue tungsten oxide metal tungsten powder; the downstream...
After calcination of ammonium tungstate into tungsten trioxide, the tungsten trioxide is reduced, and then the tungsten trioxide reduced tungsten powder is oxidized and reduced twice in a cycle, and the particle size distribution is between 0.1 and 0.5 μm. %, submicron tungsten powder with a specific surface area of...
Chemical reagent Ammonium tungstate spot
Ammonium tungstate was calcined into tungsten trioxide in air, and then submicron tungsten powder was prepared by cyclic redox method. The submicron tungsten powder prepared by the method has the advantages of less pollution, narrow particle size distribution, simple and easy process route, easy control of process...
Ammonium tungstate white powder
The particle size of the tungsten powder reduced by tungsten trioxide for the first time is not uniform, the tungsten powder with coarse particles is more, and the tungsten powder with fine particles is very little. This is consistent with the conclusion reported in the literature that tungsten trioxide is suitable...
Ammonium tungstate yellow powder
Tungsten oxide is used for many purposes in daily life. It is often used in industrial X-ray screen phosphors and fire-resistant fabrics to make tungstate. Due to its rich yellow element, tungsten oxide is also used as a pigment in ceramics and paints.
Tungsten trioxide has been employed in the production of...
