There is a strong oxidant reduction, will gradually oxidized in air, the surface will become sodium nitrate, can also be oxidized by oxidants; case of weak decomposition of brown nitrogen dioxide gas released; and organic matter, reducing agents can cause an explosion or burning of contacts and stimulating nitric oxide release toxic gases; case of strong oxidant can also be oxidized, in particular, ammonium salt, such as with ammonium nitrate, ammonium persulfate, etc. at room temperature, that is, the interaction can produce high fever, caused by fuel combustion
