Ammonium Metatungstate
Ammonium Metatungstate
Ammonium Metatungstate is a water-soluble inorganic tungsten compound belonging to the polyoxotungstate family. It is commonly supplied as a hydrate and is used as a high-purity source of tungsten in catalyst preparation, advanced materials, tungsten compound manufacturing, and chemical research. Its excellent water solubility makes it particularly useful in applications requiring tungsten to be introduced from an aqueous solution.
Our Ammonium Metatungstate is supplied under controlled quality standards to provide consistent tungsten content, chemical composition, and reliable performance for industrial, laboratory, and research applications.

Note: Ammonium Metatungstate is frequently represented as a hydrated compound, so its reported molecular weight can vary depending on the hydration state and the convention used. Commercial references list CAS 12028-48-7 for Ammonium Metatungstate Hydrate, while other commercial AMT products use CAS 12333-11-8. The exact CAS/form should therefore be matched to the grade and specification you actually sell.
Storage
Store Ammonium Metatungstate in a cool, dry, and well-ventilated area. Keep the container tightly closed when not in use and protect the product from moisture and contamination. Follow the storage conditions specified in the applicable Safety Data Sheet (SDS).
Safety Information
Handle Ammonium Metatungstate using appropriate personal protective equipment (PPE), including protective gloves, safety goggles, and suitable protective clothing. Avoid inhalation of dust and avoid contact with skin and eyes.
Depending on the specific grade and regulatory classification, Ammonium Metatungstate may cause skin irritation, serious eye irritation, or respiratory irritation. Some grades are also classified as harmful if swallowed. Always use the SDS for the exact product being supplied rather than relying on a generic classification.
Always refer to the latest Safety Data Sheet (SDS) before handling, transporting, or using the product.
