Ammonium metatungstate (AMT) is a white crystalline powder and an important tungsten chemical. It possesses good water solubility and high thermal stability, making it a key precursor in the preparation of metallic tungsten. Additionally, AMT is used in petrochemical industries to produce tungsten-based catalysts, enhances flame retardancy in fire-resistant fabrics, and improves various properties in the ceramics industry.

The performance of cut-resistant tungsten wire in high-temperature environments is significantly superior to many other metallic materials, primarily due to tungsten's inherent properties. Below is a detailed analysis of its high-temperature characteristics:

Ammonium metatungstate produced by CTIA GROUP LTD is an inorganic compound formed by the combination of ammonium ions (NH₄⁺) and complex polytungstate anions [H₂W₁₂O₄₀]⁶⁻. It is a white powder with the English name Ammonium Metatungstate (AMT), chemical formula H₂₈N₆O₄₁W₁₂, and CAS number 12333-11-8.

The chemical protection capability of cut-resistant tungsten wire is primarily manifested in its outstanding corrosion resistance, oxidation resistance, and stability in extreme chemical environments. The following is an introduction from multiple aspects:
