1.Sodium Nitrate
Cas No.: 7631-99-4
Einecs No.: 231-554-3
Formula: NaNO3
Formula weight: 84.99
Property: Colorless diamond crystal or white fine crystalline powder, also have granular form. Odorless, salty, slightly bitter. Soluble in water and ammonia, dissolved in ethanol, methanol, slightly soluble in glycerol and acetone. While being heated up to about 380 centigrade, it will decompose and release oxygen and turn into sodium nitrite; As the heating going up, it will decompose into oxygen,nitrogen and nitrogen oxide.
