The price of ammonium metatungstate (AMT) can vary depending on several factors such as the quality, quantity, purity, and supplier.
As of my knowledge cutoff date of September 2021, the price of AMT ranged from approximately $30 to $50 USD per kilogram for industrial grade material. However, prices can be higher for higher purity grades or for smaller quantities.
It’s important to note that prices are subject to change due to fluctuations in the market, availability of supply, and other factors. It’s always a good idea to check with multiple suppliers and compare prices before making a purchase.
