White or a little buff fine crystal. The relative molecular weight is 69.0 and density is 2.168. It’s no smell and a little saline taste, easy to be deliquescence and to dissolve in water. The melting point is 271°C and decomposition temperature is 320°C. It has the strong oxidizing property, as well as reducing property. It can slowly oxidize into sodium nitrite in the air, and will become diamino compound composed with ammonia under low temperature.
1)Due to its good scale inhibition and high temperature tolerance properties, is widely used in desalination plant of flash vaporization equipment, low pressure boiler, steam locomotive,crude oil evaporation, petroleum pipeline, and industrial circulating cool water systems.
2)Has good corrosion inhibition effect when used together with zinc salt.
3)Used as additives for cement.
