NaNO3 Sodium Nitrate 25 KG / BAG CAS 7631-99-4 Used for Mechanical Rust Prevention Treatment
Sodium nitrate is colorless transparent or white microribbon yellow rhomboid crystal, its taste is bitter and salty, easily soluble in water and liquid ammonia, slightly soluble in glycerin and ethanol, easy delixing, especially when containing a very small amount of sodium chloride impurities, sodium nitrate delixing is greatly increased, when dissolved in water the solution temperature is reduced, the solution is neutral when heating, sodium nitrate is easy to decompose into sodium nitrite and oxygen.
