Property: White crystal, easily absorbing moisture and be slaked in the air, easily soluble in water and alcohol. If heated above 200°C, it will be suddenly decomposed with hydrogen phosphine released. Moreover, it is a good strong reducer, and contacted with oxidizing agent, it can be exploded.
Uses:
1. Chemical plating agents: After being plated chemically, the metal surface have solid, corrosion-resistant, wear-resistant, even and compact alloy-plated layer. It can be widely applied to electronics, machines, petroleum, chemical, aviation, navigation, food, pharmaceutical etc.
2.It can add a metal layer on the surface of plastics, ceramics, glass, quartz etc.
3.Water treatment, and manufacture of various industrial corrosion preventing agent and scale inhibiting agent for oil fields.
4.Additive for food and industrial boiler water.
5.Acting as catalyst and stabilizing agent for chemical reactions.
6.Acting as antioxidant, anti-decolorizing agent, dispersing agent, as well as applicable to textile finishing and pharmaceuticals
