Ammonium Metatungstate Hydrate (CAS 12333-11-8) is a chemical compound whose significance in various industrial and research applications cannot be overstated. NINGBO INNO PHARMCHEM CO.,LTD. routinely provides this material, and understanding its fundamental chemical properties of Ammonium Metatungstate Hydrate (CAS 12333-11-8) is key to unlocking its full potential.

Visually, Ammonium Metatungstate Hydrate typically presents as a white crystalline powder. This physical characteristic is important for initial identification and handling. The compound's chemical composition, often represented by the formula (NH4)6H2W12O40·xH2O, indicates a complex polyoxometalate structure involving tungsten, ammonium ions, and water of hydration. The 'xH2O' signifies that the degree of hydration can vary, which can influence certain properties such as solubility and thermal stability.

Purity is a critical parameter for this compound. Suppliers like NINGBO INNO PHARMCHEM CO.,LTD. usually offer various grades, often specified by the minimum percentage of WO3 (Tungsten Trioxide) content. Assays of 99% or higher are common for research and industrial applications where consistent performance is required. Information on elemental content, detailing trace amounts of other metals like iron, copper, or sodium, is also vital, especially for sensitive catalytic processes where impurities can hinder effectiveness or lead to unwanted side reactions. Understanding the catalytic activity of ammonium metatungstate is directly linked to its purity profile.

Solubility is another key property. Ammonium Metatungstate Hydrate is generally soluble in water, which is advantageous for applications requiring aqueous solutions. Its pH in solution is typically in the acidic range, often between 3.0 and 6.0, depending on concentration. This acidic nature can be beneficial in certain catalytic reactions or formulations.

The thermal decomposition behavior is also an important consideration. Upon heating, Ammonium Metatungstate Hydrate will decompose, releasing ammonia and water, and eventually forming tungsten oxides. The temperature at which this decomposition occurs is a key factor in determining its suitability for high-temperature applications or processes where thermal stability is a concern.

When businesses decide to buy Ammonium Metatungstate Hydrate, they rely on suppliers to provide comprehensive data on these chemical properties. NINGBO INNO PHARMCHEM CO.,LTD. is committed to delivering materials that meet exacting standards, ensuring that clients can confidently utilize Ammonium Metatungstate Hydrate for their specific ammonium metatungstate hydrate applications, whether in catalysis, material science, or other advanced chemical fields.
