Ammonium tungstate, also called ammonium paratungstate or APT is a white crystalline salt with a chemical formula either written (NH4)10H2(W2O7)6 or (NH4)10(H2W12O42). APT is extracted from tungsten ores and is the critical raw material for the production of tungsten metal. Additionally, it is employed in the manufacturing of catalysts, pigments, and specialty chemicals. Its applications extend to the electronics industry, where it is utilized in the production of electronic components and semiconductor materials due to its excellent thermal and electrical properties. It is also a key material in the field of energy storage, particularly in the development of advanced batteries and energy-efficient devices.
Product Application:
Ammonium Paratungstate is used as a source for high-purity tungsten oxides, tungsten metal powders, carbides, or as a laboratory reagent. Other applications are in the fields of absorbent gels, coloring agent in the porcelain industry, and the catalyst industry.
