White Crystal Potassium Nitrate Fertilizer, Factory Price Potassium Nitrate KNO3
Potassium nitrate (chemical formula: KNO3) is the nitrate of potassium. It is a crystalline salt and a strong oxidizer which can be specially used in making gunpowder, as a fertilizer, and in medicine. It can be manufactured through the reaction between ammonium nitrate and potassium hydroxide, and alternatively through the reaction between ammonium nitrate with potassium chloride. Potassium nitrate has various applications. Its major applications include: fertilizer, tree stump removal, rocket propellant and fireworks. It can also be used for the nitric acid production. It is also useful for food preservation and food preparation. In pharmacology, it can be used to treat asthma and relieving high blood pressure.
Potassium nitrate is a water-soluble NK fertilizer containing 13.7% nitrate nitrogen and 46% potassium oxide (38.4%). Potassium nitrate (KNO3) is a soluble source of two major essential plant nutrients. It’s commonly used as a fertilizer for high-value crops that benefit from nitrate (NO3-) nutrition and a source of potassium (K+) free of chloride (Cl-).
Manufacturers typically make potassium nitrate fertilizer (sometimes referred to as nitrate of potash or NOP by reacting potassium chloride (KCl) with a nitrate source. Depending on the objectives and available resources, the nitrate may come from sodium nitrate, nitric acid or ammonium nitrate. The resulting KNO3 is identical regardless of the manufacturing process. Potassium nitrate is commonly sold as a water-soluble, crystalline material primarily intended for dissolving and applying with water or in a prilled form for soil application. Traditionally, this compound is known as saltpeter.
Potassium nitrate is a strong oxidant. Contact with organic matter can cause combustion and explosion. Therefore, potassium nitrate should be stored in a cool and dry place away from fire and heat source. It is forbidden to store and transport together with reducing agent, acid, combustible material and metal powder.
inhalation of this product dust is irritating to the respiratory tract, and inhalation of high concentration can cause pulmonary edema. Large amount of contact can cause methemoglobinemia, affect blood oxygen carrying capacity, and cause headache, dizziness, cyanosis, nausea and vomiting. Severe cases may cause respiratory disorder, collapse, or even death. Oral administration may cause severe abdominal pain, vomiting, bloody stool, shock, generalized convulsions, coma, and even death. It is strongly irritating to skin and eyes, even causing burns. Repeated skin contact may cause skin dryness, chaps and rashes
1. Agricultural potassium nitrate fertilizer is a pure plant nutrient, which is completely soluble in water without residual harmful substances. The nitrate nitrogen and potassium contained in it are a large number of elements necessary for crop growth. They have a good coordination effect, and can promote each other to be absorbed by crops and promote the absorption of other nutrient elements.
2. Industrial grade potassium nitrate is mainly used for heat conduction molten salt in fine chemical industry and organic chemical industry. It is also used as catalyst and beneficiation agent. Industrial grade potassium nitrate can also be used to manufacture fireworks, black powder, tobacco, chemical reagents, catalysts, ceramic glaze, glass and compound fertilizer. In addition, potassium nitrate is used as auxiliary material in metallurgical industry.
3. Photoelectric grade potassium nitrate is mainly used for chemical strengthening of high-end glass. The viscosity of potassium glass is greater than that of sodium glass, which can reduce the crystallization tendency of glass and increase the transparency and gloss of glass. Potassium nitrate can be used as a good hardening material for tempered glass to enhance hardness and increase the ability to resist falling.
