Ammonium Paratungstate Application

Ammonium paratungstate is produced separating tungsten from its ore. Once the ammonium paratungstate is prepared, it is heated to its decomposition temperature, 600 °C. Left over is WO3, tungsten(VI) oxide. From there, the oxide is heated in an atmosphere of hydrogen, reducing the tungsten to elemental powder, leaving behind water vapor. From there, the tungsten powder can be fused into any number of things, from wire to bars to other shapes.

Mainly used in the manufacture of tungsten metal powder like tungsten trioxide or tungsten blue oxide;the downstream products of metallic tungsten powder have tungsten material series, such as tungsten, tungsten and other electric vacuum materials; there are alloy series too, such as tungsten carbide alloy blade, alloy drill, alloy molds, etc.; and other wear, pressure, temperature and other machinery and equipment components.
