Product Code : AL-AMT-CU
Tungsten was used extensively for the filaments of old-style incandescent light bulbs, but these have been phased out in many countries. This is because they are not very energy efficient; they produce much more heat than light.Tungsten has the highest melting point of all metals and is alloyed with other metals to strengthen them. Tungsten and its alloys are used in many high-temperature applications, such as arc-welding electrodes and heating elements in high-temperature furnaces.
Ammonium metatungstate, also known as AMT, is a tungsten chemical in the form of highly soluble hydrated crystals. AMT is produced as a minus 10-mesh powder to meet stringent demands in the catalyst, medical, semiconductor, and other high-technology industries. AMT is also used in materials research and in analytical chemistry. At room temperature, aqueous solutions can be saturated up to 70% by weight of contained WO3. SAM provides different purity and customized packed Ammonium Metatungstate powder.
ATT is a professional supplier of Ammonium Metatungstate (AMT), We also produce disc, granules, ingot, pellets, pieces, powder, rod, wire, sputtering target and in numerous other forms and custom shapes. Other shapes are available by request.
Please contact us if you need customized services. We will contact you with the price and availability in 24 hours.

Applications of Ammonium Metatungstate (AMT)
AMT is mostly used in industries as a raw material for the production of tungsten catalysts for different systems of reactions including oxidation, hydroxylation, hydrogenation, and polymerization. Ammonium metatungstate is also used in the manufacture of various petrochemical catalysts and other tungsten compounds, and it’s the main raw material for tungsten-based catalysts in refineries.
-Reagents for chemical analysis such as for medical diagnosis
-Source material substrate for certain semiconductor devices
-High purity source medical for research in tungsten chemistry
-Source material for the DeNOx catalyst industry
-As a precursor to a variety of polyoxometalates
Packing of Ammonium Metatungstate (AMT)
