Ammonium paratungstate - Reference Information
| EPA chemical information | Information provided by: ofmpub.epa.gov (external link) |
| Overview | Ammonium paratungstate (APT) is an important tungsten intermediate product, mainly white crystals, with flake or needle. It can be used to make tungsten trioxide or blue tungsten oxide. The quality of tungsten products largely depends on the chemical purity, particle size and particle size distribution of APT. |
| application | ammonium paratungstate crystallization is the main intermediate product for preparing tungsten products blue tungsten oxide, ammonium tungsten bronze and tungsten powder. its morphology and structure greatly affect the morphology and properties of tungsten products. The particle size and bulk density of tungsten products are dependent on the raw material ammonium paratungstate. Ammonium tungsten bronze prepared by ammonium paratungstate containing different crystal water has very different properties. Di Yuying and other studies have shown that ammonium tungsten bronze made from ammonium pentahydrate and ammonium pentatungstate has good performance. |
| Use | Used as a raw material for manufacturing other tungsten compounds and metal tungsten |
