Ammonium Metatungstate (AMT), produced by CTIA GROUP LTD, primarily consists of tungsten (W), oxygen (O), nitrogen (N), and hydrogen (H), with potential impurity elements such as iron (Fe), molybdenum (Mo), vanadium (V), sodium (Na), and potassium (K). These impurities, originating from raw materials, solvents, or process conditions, significantly influence AMT’s crystal structure, physicochemical properties, and application performance.

Ammonium Metatungstate (AMT), a tungstate compound produced by CTIA GROUP LTD, consists of ammonium ions (NH₄⁺), hydrogen ions, tungstate ions, and crystal water, with the chemical formula (NH₄)₆H₂W₁₂O₄₀·xH₂O. The proportions of these components and crystal water may vary slightly depending on the preparation method and conditions. During AMT synthesis, the concentration of ammonium ions significantly influences the crystal morphology, particle size, and properties of the product, including solubility, thermal stability, chemical stability, and catalytic performance.

Ammonium metatungstate (AMT), a critical compound of the transition metal tungsten, features a core structure based on the Keggin-type polyacid anion [H₂W₁₂O₄₀]⁶⁻. This anion is formed by 12 WO₆ octahedra connected through corner- or edge-sharing, creating a cage-like structure typically centered by a heteroatom or proton. Stabilized by NH₄⁺ cations and crystal water molecules, this polyoxoanion forms a three-dimensional crystal structure. AMT’s crystal structure is generally monoclinic or triclinic, depending on crystallization conditions such as temperature, pH, and solvent. The crystal structure significantly influences AMT’s properties, including solubility, thermal stability, catalytic performance, and chemical stability. Below is a detailed analysis of these impacts.

The pH of the solution plays a critical role in the formation and stability of the crystal structure of Ammonium Metatungstate (AMT) produced by CTIA GROUP LTD. The crystal structure of AMT is centered around the Keggin-type polyacid anion [H₂W₁₂O₄₀]⁶⁻, and the pH directly influences the polymerization behavior of tungstate ions, which in turn affects the formation, chemical composition, and morphology of the crystals.

Ammonium Metatungstate (AMT) is a critical tungsten compound primarily used in the production of tungsten powder, tungsten wire, tungsten alloys, and hard alloys. It finds extensive applications in electronics, aerospace, mechanical manufacturing, catalysis, and the chemical industry. The physicochemical properties of AMT, such as solubility, thermal stability, and catalytic performance, are influenced by factors including crystal structure, solution pH, preparation temperature, and other conditions.
