Ammonium paratungstate (APT) is a white crystalline powder with chemical formula (NH4) 10 [H2W12O42] • 4H2O, which is an important compound of tungsten. It is usually used to prepare other tungsten compounds and is also an important intermediate of tungsten.
In industry, ammonium paratungstate is one of the main raw materials for extracting tungsten from tungsten ores. After a series of chemical treatment of tungsten ore, ammonium paratungstate is finally obtained. In addition, ammonium paratungstate is also used to prepare tungsten compounds such as ammonium tungstate and sodium tungstate. In addition, ammonium paratungstate is also widely used in electronic industry, metallurgical industry, aerospace industry and other fields.
