Ammonium metatungstate (AMT) is a highly water-soluble tungstate compound, widely used in tungsten chemical industries and catalyst preparation due to its high solubility in water (approximately 300-330 g/100 mL at 25°C). However, its solubility in organic solvents is significantly different, typically much lower or nearly insoluble. Below is an overview of AMT's solubility in some common organic solvents:

Ammonium metatungstate (AMT) is an important tungsten compound, appearing as a white crystalline powder, primarily used in the production of tungsten powder, tungsten wire, hard alloys, and in fields such as petrochemicals, catalysts, and ceramics. Besides being soluble in water and certain organic solvents, AMT can also dissolve in dilute acid solutions.

Ammonium metatungstate (AMT), besides being soluble in dilute acid solutions such as dilute hydrochloric acid, dilute nitric acid, and acetic acid, can also dissolve in alkaline solutions like ammonia water.

The solubility of ammonium metatungstate (AMT) in water is one of its key physicochemical properties, attracting significant attention due to its wide applications in industry, catalyst preparation, and tungsten compound production.
