Sodium nitrate is colorless transparent or white yellow rhomboid crystal, its taste salty, easy to dissolve in water and liquid ammonia, slightly soluble in glycerol and ethanol, easy delixing, especially when containing a very small amount of sodium chloride impurities, sodium nitrate delixing is greatly increased, when dissolved in water when the solution temperature decreases, the solution is neutral, when heating, sodium nitrate is easy to decompose into sodium nitrite and oxygen. So, what are the application areas and precautions of sodium nitrate? Zibo Qifan to share with you, let's see!

Application field of sodium nitrate

1, enamel industry used as flux, oxidant and raw materials for preparation of enamel powder.

2, glass industry used as a variety of glass and products of decolorization agent, defoamer, clarifying agent and oxidation flux.

3, no hunger industry used as a decolorizing agent of molten caustic soda and for the manufacture of other nitrates.

4, food industry used as meat processing hair color agent, can prevent meat spoilage, and can play the role of seasoning.

5, fertilizer industry used as a quick fertilizer suitable for acid soil, especially suitable for root crops, such as beet, radish, etc. The dye industry is used as a raw material to produce picric acid and dyes.

6, metallurgical industry used as steel, aluminum alloy heat treatment agent. Machine city industrial used as metal cleaning agent and preparation of black metal bluing agent.

7, the pharmaceutical industry used as a medium for penicillin. The cigarette industry is used as an accelerant for tobacco.

8, analytical chemistry used as chemical reagents, in addition, also used in the production of explosives.

Sodium nitrate for use

    Sodium nitrate is mainly used as corrosion inhibitor and boiler metal embrittlement inhibitor in the field of water treatment. When sodium nitrate is used as metal embrittlement inhibitor, it should be used in combination with sodium hydroxide, and maintain a certain proportion. The embrittlement of metal materials can be prevented by adding sodium nitrate into the low pressure boiler system. In addition, there are many other areas of use.

    Sodium nitrate can help prevent food spoilage and ensure safe human consumption. Large doses can be used in insecticides and rodenticides. In addition, sodium nitrate has many industrial uses, including fertilizer, photochemical and metal casting industries.

    Sodium nitrate is also a salt used to make fertilizers, explosives and rocket propellants. Sodium nitrate is also used as a preservative to preserve meat. Sodium nitrate has antibacterial properties that prevent carrion poisoning, and many people may not know that some green leafy vegetables also contain high amounts of sodium nitrate.

    Nitrate and nitrite are known to be closely related to cardiovascular diseases. Excessive consumption of processed meats such as ham and sausage is likely to lead to cardiovascular diseases such as hypertension and arteriosclerosis. Experts warn that consuming too much meat with sodium nitrate can also cause migraines.

Sodium nitrate was first mined in Chile's Atacama Desert, the driest desert on Earth. The Atacama is also one of the most mineral-rich regions. Despite concerns about the negative health effects of sodium nitrate, its absence would make it very difficult to store and transport meat, which spoils easily.

Precautions for using sodium nitrate

1. Health hazards. Irritant to skin and mucous membrane. Oxidize ferrous iron in the blood to high iron, losing the ability to carry oxygen. Severe abdominal pain, vomiting, bloody stools, shock, convulsions, coma, and even death can occur during mass oral poisoning.

2. Ignition and explosion risk. Strong oxidation, contact with organic matter or phosphorus, sulfur, friction or impact can cause combustion and explosion.
