Sodium nitrate, an inorganic compound with the formula NaNO3, is a hygroscopic colorless transparent triangulation crystal. It decomposes when heated to 380℃. Highly soluble in water, liquid ammonia, soluble in methanol and ethanol, very slightly soluble in acetone, slightly soluble in glycerol. When dissolved in water, it absorbs heat, the solution becomes cold, and the aqueous solution is neutral. Used in the production of nitric acid, sodium nitrite, glass, matches, enamel or ceramic industry ingredients, fertilizer, sulfuric acid industry in the catalyst.

Product Purpose
Sodium nitrate is the raw material for the manufacture of potassium nitrate, mine explosives, picric acid, dyes and so on. Nitrating agent for making dye intermediates. Glass industry used for the production of various glass and its products defoamer, decolorizer, clarifying agent and oxidation flux. The enamel industry is used as oxidant and flux for the preparation of enamel powder. Mechanical industry used as metal cleaning agent, also used in the preparation of black metal bluing agent. Metallurgical industry used as steel and aluminum alloy heat treatment agent. The light industry is used as an accelerant for the manufacture of cigarettes. The pharmaceutical industry uses it as a culture medium for penicillin. The fertilizer industry is used as a quick-acting fertilizer suitable for acidic soils, especially for root crops such as beets and radishes. It is also used as a decolorizing agent for molten caustic soda. High purity analytical reagents, spectral reagents, oxidants, also used in dye synthesis and the manufacture of explosives and fireworks. Nitrates have early strength effects, especially at low temperature, negative temperature as early strength, antifreeze. Used as a corrosion inhibitor and desensitization agent in toothpaste to prevent dentin allergy. Sodium nitrate is mainly used as corrosion inhibitor and boiler metal embrittlement inhibitor in the field of water treatment. In addition, there are many other fields of use. The addition of sodium nitrate in the low-pressure boiler system inhibits the corrosion of metal on the water side and prevents the embrittlement of metal materials. When sodium nitrate is used as a metal embrittlement inhibitor, it needs to be combined with sodium hydroxide and maintain a certain proportion. Electroplating grade or chemically pure sodium nitrate can be used to add black chromium to electroplating, can also be used in black chromium plating electrolyte, and low chromic acid passivation of zinc coating, zinc dipping, magnesium and magnesium alloy oxidation solutions.
