CTIA GROUP LTD ammonium metatungstate picture

Ammonium metatungstate (AMT), a typical transition metal compound, appears as a white crystalline powder or slightly yellowish powder, with the molecular formula H28N6O41W12 and a density of 2.3-2.8 g/cm³. It has a wide range of applications. In the field of catalysis, AMT excels as a catalyst and support for reactions like hydrogenation and dehydrogenation in petrochemical processes. In functional materials, it is used to prepare tungsten-based energy storage materials and electrochromic materials. AMT is also utilized in producing ultrafine tungsten powder, tungsten alloys, as well as serving as an analytical reagent and an additive in ceramic materials.
