Ammonium metatungstate (AMT), with the molecular formula H₂₈N₆O₄₁W₁₂, is a significant tungstate compound. Structurally, AMT consists of ammonium cations and metatungstate anions, with its unique Keggin-type polyoxoanion structure contributing to its excellent solubility—a key distinction from ammonium paratungstate.

Ammonium metatungstate (AMT) is a compound formed by the combination of ammonium cations and metatungstate anions, typically appearing as a white crystalline powder with good water solubility and chemical stability. These properties lay a solid foundation for its applications in catalysts, electronics, ceramics, and other fields. Given its wide-ranging uses, research into AMT production methods is of great importance, as it directly impacts product quality, performance, production costs, and efficiency.

Silver tungsten carbide (AgWC) is a high-performance composite material composed of silver (Ag) and tungsten carbide (WC), usually prepared by powder metallurgy technology. This material combines the electrical advantages of silver and the mechanical strength of tungsten carbide, and has both conductive and wear-resistant properties. It plays an indispensable role in electrical engineering and is often used to manufacture electrical contacts with excellent stability and durability.

In the vast universe of materials science, ammonium metatungstate (AMT) shines like a unique and dazzling star, exuding captivating charm. This inorganic compound, with its excellent physicochemical properties, holds a pivotal position in modern industry and cutting-edge scientific research.
