Ammonium metatungstate (AMT) and ammonium paratungstate (APT) are two common tungsten compounds, differing in chemical composition, physicochemical properties, applications, and production processes.

The thermal decomposition process of ammonium metatungstate (AMT) is a complex, multi-stage reaction involving the removal of crystal water, structural phase transitions, and the eventual formation of tungsten oxide. Specifically, the thermal decomposition of AMT can be pided into the following stages:

Ammonium metatungstate (AMT), as an important inorganic compound, possesses unique physicochemical properties and is widely used in ceramics, textiles, and catalysts. AMT has the following characteristics:

The wire cut molybdenum wire is a molybdenum product mainly made of refractory metal molybdenum (Mo). It is a thin wire made by forging and drawing molybdenum bars, and serves as a cutting wire for wire cutting machines. Its English name is "wire cut molybdenum wire", and its diameter generally ranges from 0.12 to 0.20 mm.
