High Quality Factory Price Technical Grade Sodium Nitrate CAS 7631-99-4
1. Product Introduction
Sodium nitrate is an inorganic compound. Its chemical formula is nano3. Sodium nitrate is a humidity -absorbent colorless transparent triangular crystal. When heating to 380 ° C, sodium nitrate can be decomposed. It is easily soluble in water and liquid ammonia, can be dissolved in methanol and ethanol, extremely slightly soluble in acetone, and slightly soluble in glycerin. When it dissolves in water, it absorbs heat, the solution becomes cold, and the aqueous solution is neutral. It can be used to make nitric acid, sodium nitrite, as glass, matches, enamel or ceramic industry ingredients, fertilizers, catalysts in the sulfuric acid industry, etc.Sodium nitrate is an inorganic compound.
