Tungsten powder is the basic raw material for making cemented carbide.
At present, the industrial production of pure tungsten trioxide or APT is mainly purify the crude sodium tungstate solution.
Tungsten powder is mainly used to manufacture tungsten filament for incandescent lamp, inert gas shielded arc welding and atomic hydrogen welding electrode etc..
In recent years, tungstate catalysts have attracted more attention for their narrower band gap and larger visible light range.
Many scholars have tried new methods to reduce production cost. The direct synthesis of tungsten cobalt alloy powder from ammonium metatungstate is an innovative attempt.
High purity quaternary ammonium paratungstate (APT) is a crystalline powder of ammonium paratungstate with a purity of 99.999% to 99.9999%.
Tungsten trioxide is a transition metal oxide, with a semiconductor character, has great potential for gas-sensitive materials, sensitive to a variety of gases, especially toxic gases.
