Ammonium Metatungstate is shorted to AMT. it is a kind of white crystal powder, which is manufactured by ion exchange. The method is used ammonium paratungstate(APT) as raw material. The purity can be controlled over 90.00%. AMT is widely used in industries, such as petroleum, chemicals, ceramic and lubricant. Meanwhile, it can also be used as catalyst.
