Sodium nitrate is an inorganic compound with the chemical formula NaNO3. It is a hygroscopic colorless transparent triangular crystal. Decompose when heated to 380 ℃. Extremely soluble in water and liquid ammonia, soluble in methanol and ethanol, slightly soluble in acetone, and slightly soluble in glycerol. When dissolved in water, it absorbs heat, cools the solution, and the aqueous solution becomes neutral.
Usage: Used for the production of nitric acid and sodium nitrite, as ingredients in glass, matches, enamel or ceramic industries, fertilizers, catalysts in sulfuric acid production, etc. Sodium nitrate is a raw material for manufacturing potassium nitrate, mining explosives, picric acid, dyes, and so on. Nitrating agents for manufacturing dye intermediates. The metallurgical industry is used as a heat treatment agent for steelmaking and aluminum alloys. The fertilizer industry is used as a quick acting fertilizer suitable for acidic soils, particularly suitable for root crops such as sugar beets and radishes. It is also used as a decolorizing agent for molten caustic soda. High purity analytical reagents, spectroscopic reagents, oxidants, and also used in dye synthesis and the manufacture of explosives and fireworks. Sodium nitrate is mainly used as a corrosion inhibitor and an inhibitor of boiler metal embrittlement in the field of water treatment. In addition, it has a wide range of applications in other fields. Add sodium nitrate to the low-pressure boiler system to suppress corrosion of water side metals and prevent metal material embrittlement. When sodium nitrate is used as a metal embrittlement inhibitor, it needs to be combined with sodium hydroxide and maintained in a certain proportion. Electroplating grade or chemically pure sodium nitrate can be used as an additive for electroplating black chromium, as well as in black chromium plating electrolytes, as well as in low chromium passivation of zinc coatings, oxidation solutions for zinc immersion, magnesium, and magnesium alloys.
