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!

　　硝酸鈉的應用

　　7. 制藥業把它用作青霉素的培養基。卷煙工業被用作煙草的促進劑。

　　7. The pharmaceutical industry uses it as a culture medium for penicillin. The cigarette industry is used as an accelerant of tobacco.

　　8. 在分析化學中，它被用作化學試劑。此外，它還用于生產炸藥。

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

　　硝酸鈉的使用

　　Use of sodium nitrate

　　硝酸鈉在水處理領域主要用作緩蝕劑、鍋爐金屬脆化抑制劑。硝酸鈉作為金屬脆化抑制劑時，應與氫氧化鈉配合使用，并保持一定比例。在低壓鍋爐系統中加入硝酸鈉可以防止金屬材料的脆化。此外，其他領域也得到了廣泛的應用。

　　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.

　　硝酸鈉可以防止食物變質，保證食用。大劑量可用于殺蟲劑和殺鼠劑。此外，硝酸鈉還有許多工業用途，包括化肥、光化學和金屬鑄造工業。

　　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.

　　硝酸鈉也是一種用于生產化肥、炸藥和火箭推進劑的鹽。硝酸鈉的使用還包括作為防腐劑保存肉類。硝酸鈉具有特性，可以防止腐肉中毒，許多人可能不知道一些綠葉蔬菜也含有大量的硝酸鈉。

　　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.

　　眾所周知，硝酸鹽和亞硝酸鹽與心血管疾病密切相關，而過量食用加工肉類，如火腿和香腸，則與高血壓和動脈硬化等心血管疾病有關。警告說，食用過多的含硝酸鈉的肉類也會導致偏頭痛。

　　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.

　　硝酸鈉初開采于智利的阿塔卡馬沙漠，這是地球上干燥的沙漠。阿塔卡馬也是礦產豐富的地區之一。盡管硝酸鈉對健康有負面影響，但缺乏硝酸鈉會使肉類難以儲存和運輸，容易變質。

　　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.
