Synthesis of Ammonium Paratungstate (APT) From Double Ammonium-Sodium Paratungstate

SEM image of DSAP and APT

The conventinal autoclave soda leaching is a mature method for treating tungsten concentrate, where tungsten concentrate reacts with sodium carbonate to produce sodium tungstate. And finally through ion exchange and evaporative crystallization, ammonium paratungstate (APT) was manufactured. However the mass waste water is produced during the process.

Study on the Performance of WS2 and WS2-C Composite Film

WS2 thin film photo

As an important solid lubricating material, tungsten disulfide has a wide range of applications in aerospace, machining, new energy vehicles, medical, electronics, digital and other fields due to its excellent tribological properties. However, the carrying capacity of pure WS2 film is low, and it is easy to absorb moisture and oxidize in humid air, which seriously shortens its service life.
