Sodium nitrate is a colorless transparent or white micro strip yellow diamond crystal, which tastes bitter and salty, soluble in water and liquid ammonia, slightly soluble in glycerin and ethanol, and easy to be deliquesced, especially in a very small amount of sodium chloride impurities, the deliquesce of sodium nitrate is greatly increased, when dissolved in water, when the solution temperature is reduced, the solution is neutral, when heated, sodium nitrate is easy to be decomposed into sodium nitrite and oxygen. So, what are the application fields and precautions of sodium nitrate? Hengyi chemical will share with you and look at them together!

　　8. In analytical chemistry, it is used as a chemical reagent. It is also used in the production of explosives.

　　硝酸钠的使用

　　Use of sodium nitrate

　　硝酸钠在水处理领域主要用作缓蚀剂、锅炉金属脆化抑制剂。硝酸钠作为金属脆化抑制剂时，应与氢氧化钠配合使用，并保持一定比例。在低压锅炉系统中加入硝酸钠可以防止金属材料的脆化。此外，其他领域也得到了广泛的应用。

　　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 the inhibitor of metal embrittlement, it should be used together with sodium hydroxide and keep a certain proportion. Adding sodium nitrate to the low pressure boiler system can prevent the embrittlement of metal materials. In addition, other fields have also been widely used.

　　硝酸钠可以防止食物变质，保证食用。大剂量可用于杀虫剂和杀鼠剂。此外，硝酸钠还有许多工业用途，包括化肥、光化学和金属铸造工业。

　　Sodium nitrate can prevent food from spoilage and ensure safe consumption. Large doses can be used in insecticides and rodenticides. In addition, sodium nitrate has many industrial uses, including chemical fertilizer, photochemistry and metal casting industry.

　　硝酸钠也是一种用于生产化肥、炸药和火箭推进剂的盐。硝酸钠的使用还包括作为防腐剂保存肉类。硝酸钠具有特性，可以防止腐肉中毒，许多人可能不知道一些绿叶蔬菜也含有大量的硝酸钠。

　　Sodium nitrate is also a salt used in the production of fertilizers, explosives and rocket propellants. The use of sodium nitrate also includes preservation of meat as a preservative. Sodium nitrate has antibacterial properties and can prevent carrion poisoning. Many people may not know that some green leafy vegetables also contain a lot of sodium nitrate.

　　众所周知，硝酸盐和亚硝酸盐与心血管疾病密切相关，而过量食用加工肉类，如火腿和香肠，则与高血压和动脉硬化等心血管疾病有关。警告说，食用过多的含硝酸钠的肉类也会导致偏头痛。

　　As we all know, nitrate and nitrite are closely related to cardiovascular diseases, while excessive consumption of processed meat, such as fire legs and sausages, is related to cardiovascular diseases such as hypertension and arteriosclerosis. Experts warn that eating too much meat with sodium nitrate can also cause migraines.

　　硝酸钠初开采于智利的阿塔卡马沙漠，这是地球上干燥的沙漠。阿塔卡马也是矿产丰富的地区之一。尽管硝酸钠对健康有负面影响，但缺乏硝酸钠会使肉类难以储存和运输，容易变质。

　　Sodium nitrate was originally mined in Chile's Atacama Desert, the driest desert on earth. Atacama is also one of the most mineral rich areas. Although sodium nitrate has a negative impact on health, the lack of sodium nitrate will make meat difficult to store and transport, and easy to deteriorate.
