Product review


Product Description:

Potassium nitrate is an inorganic substance with the chemical formula KNO3, which refers to potassium nitrate. The composition can be regarded as containing 13% nitrogen and 45% potassium oxide. Commonly known as fire nitrate or soil nitrate. The relative molecular mass is 101.10. It is colorless and transparent orthorhombic crystals or rhombic crystals or white powder, odorless, non-toxic, salty and refreshing. It absorbs little moisture in the air and is not easy to agglomerate. The relative density is 2.019 (16°C), the melting point is 334°C, it is easily soluble in water, and the solubility increases rapidly with the increase of temperature. It is soluble in liquid ammonia and glycerin, but insoluble in anhydrous ethanol and ether. Potassium nitrate is a chlorine-free nitrogen-potassium compound fertilizer with high solubility. Its effective components nitrogen and potassium can be quickly absorbed by crops without chemical residues. Used as fertilizer, it is suitable for vegetables, fruits and flowers, and some chlorine-sensitive crops (such as potatoes, strawberries, beans, cabbage, lettuce, peanuts, carrots, onions, blueberries, tobacco, apricots, grapefruit and avocados, etc.). Potassium nitrate is a strong oxidant, which can cause combustion and explosion when it comes in contact with organic matter. Therefore, potassium nitrate should be stored in a cool and dry place, away from fire and heat sources. Do not store and transport it with reducing agents, acids, combustibles, and metal powders.
