Ammonium Metatungstate, abbreviated as AMT, is a metallic tungsten chemical and is in the form of highly soluble hydrated crystals. Ammonium Metatungstate is mainly used in industry as a raw material for the production of tungsten catalysts and in different chemical reaction systems, including oxidation, hydroxylation, hydrogenation and polymerization systems.
Ammonium metatungstate (AMT) is a compound formed by the combination of an ammonium cation and a metatungstate anion. Ammonium metatungstate (AMT), with the chemical formula (NH4)6[H2W12O40], is a complex salt commonly used as a precursor for the production of tungsten powder and other tungsten compounds.
Ammonium metatungstate has a white crystalline appearance and is soluble in water. It is highly thermally stable and can withstand high temperatures without failure, making it suitable for a variety of industrial and technical applications.
The production of ammonium metatungstate involves the reaction of ammonium hydroxide and tungsten trioxide. This reaction produces a white crystalline solid, which is then purified and dried to produce a high purity product. The purity of the product is an important factor in determining its suitability for different applications.
Ammonium metatungstate has many uses in a variety of industries, including the electronics, aerospace and chemical industries. In the electronics industry, it is used as a precursor for the production of tungsten films and interconnects. In the aerospace industry, it is used to produce tungsten-based alloys and coatings. In the chemical industry, it is used to produce tungsten-based catalysts.
Despite its many uses, it is important to consider the safety implications associated with ammonium metatungstate. The compound is toxic if ingested and can cause skin irritation if it comes into contact with the skin. It is also flammable and should be stored and handled carefully to avoid fire hazards.
