Ammonium Metatungstate (AMT) can be produced through the following steps:
Tungstate dissolution: Dissolve tungstate (such as sodium tungstate) in an appropriate amount of hot water to form a tungstate solution.
Filtration: Filter the tungstate solution to remove impurities and insoluble substances.
Crystallization: The filtered tungstate solution is heated and concentrated, and gradually cooled to promote the formation of tungstate crystals.
Precipitation and filtration: The formed tungstate precipitate is separated by filtration or centrifugation to obtain solid tungstate.
Ammonization reaction: react solid tungstate with ammonia water or ammonia gas for ammonization reaction to generate ammonium metatungstate.
Crystallization and drying: The formed ammonium metatungstate solution is crystallized and dried to convert it into solid ammonium metatungstate.
Crushing and Refining: The solid ammonium metatungstate is pulverized and refined to obtain the desired purity and particle size.
It should be noted that the specific preparation methods and operating conditions may vary with different manufacturers and processes. This is just a general production process. For detailed steps and parameters, you may need to refer to specific literature or inquire with related manufacturers.
Please note that when conducting any chemical experiment or industrial production process, proper safety operation and protective measures should be followed, and relevant regulations and regulations should be followed.
