Sodium Nitrate NaNo3 25kg Price

Sodium nitrate is an inorganic compound with the chemical formula NaNO3. It is a hygroscopic colorless transparent triangular crystal. It decomposes when heated to 380°C. It is very soluble in water and liquid ammonia, soluble in methanol and ethanol, very slightly soluble in acetone, and slightly soluble in glycerol. It absorbs heat when dissolved in water, the solution becomes cold, and the aqueous solution is neutral. It is used to make nitric acid and sodium nitrite, as an ingredient in the glass, match, enamel or ceramic industry, fertilizer, catalyst in the sulfuric acid industry, etc.

Sodium nitrate is the raw material for making potassium nitrate, mining explosives, picric acid, dyes, etc. It is a nitrating agent for making dye intermediates. It is used as a defoamer, decolorizer, clarifier and oxidizing flux in the glass industry for the production of various glasses and their products. It is used as an oxidant and flux in the enamel industry for the preparation of enamel powder. It is used as a metal cleaning agent in the machinery industry and also used to prepare a blueing agent for black metals. It is used as a heat treatment agent for steelmaking and aluminum alloys in the metallurgical industry. It is used as a combustion aid in the manufacture of cigarettes in the light industry. It is used as a culture medium for penicillin in the pharmaceutical industry. It is used as a quick-acting fertilizer suitable for acidic soils in the fertilizer industry, especially for root crops such as beets and radishes. It is also used as a decolorizing agent for molten caustic soda. It is a high-purity analytical reagent, spectral reagent, oxidant, and is also used in dye synthesis and the manufacture of explosives and fireworks. Nitrates all have an early strength effect, especially as an early strength and antifreeze agent at low temperatures and negative temperatures. It is 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 is also widely used in other fields. Sodium nitrate is added to the low-pressure boiler system to inhibit the corrosion of water-side metals and prevent the embrittlement of metal materials. When sodium nitrate is used as a metal embrittlement inhibitor, it needs to be used in combination with sodium hydroxide and maintain a certain ratio. Electroplating grade or chemically pure sodium nitrate can be used for the addition of black chrome electroplating, and can also be used in black chrome plating electrolytes, as well as low-chromic acid passivation of zinc coatings, zinc immersion, and oxidation solutions of magnesium and magnesium alloys.
