1. Used for the production of nitric acid and sodium nitrite, as ingredients in the glass, match, enamel or ceramic industries, fertilizers, catalysts in the sulfuric acid industry, etc.
2. Sodium nitrate is a raw material for manufacturing potassium nitrate, mining explosives, picric acid, dyes, etc. A nitrating agent for manufacturing dye intermediates.
3. The glass industry is used as a defoamer, decolorizer, clarifier, and oxidizing flux for the production of various types of glass and its products.
4. The enamel industry is used as an oxidant and flux for preparing enamel powder. The mechanical industry is used as a metal cleaning agent and also for preparing black metal blueing agents.
5. Sodium nitrate metallurgical industry is used as a heat treatment agent for steelmaking and aluminum alloys. Sodium nitrate is used as a combustion aid in the manufacturing of cigarettes in light industry. The pharmaceutical industry uses penicillin as a culture medium.
6. Sodium nitrate fertilizer industry is used as a quick acting fertilizer suitable for acidic soil, especially suitable for root crops such as sugar beets and radishes. It is also used as a decolorizing agent for molten caustic soda.
7. High purity analytical reagents, spectroscopic reagents, oxidants, and also used in dye synthesis and the manufacturing of explosives and fireworks. Nitrates all have an early strengthening effect, especially as early strengthening and antifreeze agents at low and negative temperatures.
8. Sodium nitrate is used as a corrosion inhibitor and desensitizer in toothpaste to prevent dentin hypersensitivity. Sodium nitrate is mainly used as a corrosion inhibitor and an inhibitor for boiler metal embrittlement in the field of water treatment.
In addition, other fields have a wide range of applications. Sodium nitrate is added 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 mixed 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 in electroplating. Sodium nitrate can also be used in black chromium plating electrolytes, as well as low chromic acid passivation of zinc coatings, zinc immersion, magnesium and magnesium alloy oxidation solutions.
