GB/T 4553-2016 NaNO3 Sodium Nitrate 25 KG / BAG for Glass and Explosive
Sodium nitrate is colorless and transparent rhombus crystals, or white or slightly yellow granules or powder at room temperature. It tastes salty and slightly bitter. It is easily deliquescent in moist air. When water is dissolved, the temperature drops and the aqueous solution becomes neutral. Sodium nitrate is an oxidant that can cause combustion and explosion when in contact with organic matter such as sawdust, cloth, and oil. Sodium nitrate is oxidizing and can react with lead to produce sodium nitrite and lead oxide. It can also oxidize hydroiodic acid to iodine and form nitric oxide at room temperature: Sodium nitrate solution will show the characteristics of nitric acid after the introduction of hydrogen ions: Sodium nitrate is one of the ingredients of pickling salt.

1. Used as analytical reagents, such as oxidants, sample additives in emission spectroscopy analysis. It can also be use d to synthesize dyes, drugs, and make fireworks and explosives.
2. Used as a corrosion inhibitor and desensitizer in toothpaste to prevent dentin allergy. It can also be used in the preparation of enamel, glass industry, dye intermediates, drugs, and gunpowder.
3. It is a raw material for the manufacture of potassium nitrate, mining explosives, picric acid, dyes, etc. It is a nitrating agent for the manufacture of dye intermediates. The glass industry is used as a defoamer, decolorizer, clarifier, and oxidizing flux for the production of various glasses and their products. The enamel industry is used as an oxidant and flux for the preparation of enamel powder.
4. Nitrates have the effect of early strength, especially as early strength and antifreeze at low temperatures and negative temperatures. It is also a raw material for the manufacture of potassium nitrate, mining explosives, picric acid, and dyes. It is used as a nitrating agent for the manufacture of dye intermediates. It is also used as a defoamer, oxidant, flux, cleaning agent, ferrous metal bluing agent, and combustion aid, etc.
5. 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 a certain ratio must be maintained.
