Cas no 12028-48-7 (Ammonium metatungstate hydrate)
Ammonium metatungstate hydrate (AMT) is a white crystalline powder with the chemical formula (NH?)?[H?W??O??]·xH?O. It is highly soluble in water and serves as a key precursor in the production of tungsten-based materials, including catalysts, ceramics, and coatings. AMT exhibits excellent thermal stability and can be decomposed to yield high-purity tungsten oxides or metallic tungsten under controlled conditions. Its uniform particle size and high purity make it suitable for advanced applications in electronics, energy storage, and chemical synthesis. The hydrate form ensures consistent reactivity and ease of handling in industrial processes. AMT is valued for its precise stoichiometry and compatibility with various synthesis routes, enhancing its utility in research and manufacturing.
