Ammonium paratungstate (APT) is an important intermediate in the process of tungsten metallurgy. With APT, most tungsten products can be produced. The conventional methods for most of the commercial production of APT are caustic soda leaching and soda ash leaching.

Tungsten granule is widely used as accelerator and catalyst in carbon sulfur analyzer to test the content of carbon and sulfur.

WO3 is a popular and least bothered an n-type semiconductor with promising electrochemical properties, a high surface area, a small pore-size distribution, with several exciting chemical and physical properties, which have made it a appropriate material for various applications such as catalysts, gas sensors, and energy storage applications[5]. Up till, myriads of chemical and physical preparation methods like thermal evaporation, chemical vapor deposition, the sputtering, and colloidal suspension, have been applied for the synthesis of WO3 nanostructures of different phases and morphologies; nanoparticles, nanofiber, nanorods and nanowires. All reported synthesis methods could be either expensive, time consuming or tedious, with huge hazardous waste as toxic byproducts.

Tungsten alloy shielding is made by tungsten nickel copper alloy or tungsten nickel iron alloy instead of lead or steel, and used to shield the radiations.
