Ammonium Paratungstate(APT)is a white crystalline powder with CAS No. 11120-25-5. It features high purity and stable chemical properties, serving as an important intermediate in tungsten chemical processes.
APT can be easily converted into tungsten trioxide (WO₃) or blue tungsten oxide (BTO) powders and can also be used to produce tungsten carbide, ammonium metatungstate, and other tungsten compounds.
Applications and Uses: Ammonium Paratungstate (APT) is widely used in the production of cemented carbides, electronic materials, catalysts, and high-tech tungsten chemicals. It serves as a key raw material for tungsten trioxide, blue tungsten oxide (BTO) powders, metallic tungsten, and other tungsten compounds, supporting upstream and downstream processing needs within the tungsten industry.
