Tungsten and molybdenum alloys have excellent corrosion resistance to liquid zinc and are used to make agitators, pipes and container liners and other components in zinc smelting industry. It can be used as a high temperature component in rocket and missile, the filament of the electron tube, parts and other high temperature materials for the corresponding high temperature conditions.

Hot spray welding (coating) technology has made rapid progress. There have been high energy plasma spraying, vacuum plasma spraying, supersonic flame spraying, explosive spraying and other new technologies, which can improve the performance of the coating more than the existing oxygen one acetylene flame spraying. Moreover, the hard alloy hot spray welding (coating) powder is convenient to make, no matter which kind of technology is used, the raw material of the spray can not be carbonized.

The electric contact is the key element of the switchgear. It bears the function of conducting current, its performance directly affects the reliability and service life of the switching apparatus. Therefore, the switch electrical contact should have good electrical conductivity, high resistance to welding and corrosion resistance and so on.

Tungsten and molybdenum are important non-ferrous metals. They are mainly used in alloy metallurgy, but also widely used in other fields such as chemical industry. As the price of tungsten and molybdenum products has increased in recent years, Recovering APT, tungsten and molybdenum from the slag in the production of ammonium paratungstate (APT) can create better economic benefits for enterprises.
