NaNO3 Sodium Nitrate Chemicals Sodiumnitrate CAS Number 7631-99-4

NaNO3 Inorganic raw materials of sodium nitrate for chemical and ceramic industries

Product Introduction:

Sodium nitrate is an inorganic compound with the chemical formula NaNO3. It is a hygroscopic, colorless, transparent triangular crystal. Decompose when heated to 380 ℃. Very soluble in water and liquid ammonia, soluble in methanol and ethanol, and slightly soluble in glycerol. When dissolved in water, it absorbs heat, the solution cools, and the aqueous solution becomes neutral.

Product Usage:

Sodium nitrate is a raw material used in the production of potassium nitrate, mining explosives, picric acid, dyes, etc. Nitrifying agent for manufacturing dye intermediates. The glass industry is used as a defoamer, decolorizer, clarifying agent, and oxidizing flux for the production of various types of glass and its products. Enamel is used in the enamel industry as an oxidant and flux for preparing enamel powder. Used in the mechanical industry as a metal cleaning agent and also in the formulation of black metal blueing agents. Used as a steelmaking and aluminum alloy heat treatment agent in the metallurgical industry. Light industry is used as a combustion enhancer for manufacturing cigarettes. Used as a culture medium for penicillin in the pharmaceutical industry. The fertilizer industry is used as a quick acting fertilizer suitable for acidic soils, especially 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 are also used in dye synthesis and the manufacture of explosives and fireworks. Nitrates all have early strength effects, especially as early strength and antifreeze agents at low and negative temperatures. Used as a corrosion inhibitor and desensitizer in toothpaste to prevent dentin allergies. 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 the corrosion of metal on the water side and prevent the embrittlement of metal materials. When sodium nitrate is used as a metal embrittlement inhibitor, it needs to be compounded with sodium hydroxide and maintained in a certain proportion. Electroplating grade or chemically pure sodium nitrate can be used for the addition of black chromium plating, as well as in black chromium plating electrolytes, and in low chromium passivation, zinc immersion, magnesium and magnesium alloy oxidation solutions for galvanized layers.
