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. Its chemical formula

3. Product Application
Sodium nitrate is a raw material for manufacturing potassium
nitrate, mining explosives, picric acid, dyes, etc. Sodium nitrate
is a nitrating agent used in the production of dye intermediates.
In the glass industry, it is used as a defoamer, decolorizer,
clarifier, and oxidation flux in the production of various glass
and glass products. In the enamel industry, sodium nitrate can be
used as an oxidant and flux for preparing enamel powder. In the
mechanical industry, sodium nitrate can be used as a metal cleaning
agent and also in the preparation of black metal blueing agents. In
the metallurgical industry, it can be used as a heat treatment
agent for steelmaking and aluminum alloys.
