Sodium nitrate is an inorganic substance with the chemical formula of NaNO3. Molecular weight 84.99. Hygroscopic colorless transparent triangular crystal. Decompose when heated to 380 ℃. It is very soluble in water and liquid ammonia, soluble in methanol and ethanol, more soluble in acetone and slightly soluble in glycerol. When dissolved in water, it absorbs heat, the solution becomes cold, and the aqueous solution is neutral. It is formed by absorbing nitrogen oxides from industrial alkali solution and evaporation crystallization. It is used for manufacturing nitric acid and sodium nitrite, as ingredients in glass, match, enamel or ceramic industry, fertilizer and catalyst in sulfuric acid industry, etc.
