CAS 7757-79-1 Potassium Nitrate, Hot Sale White Crystal Industrial Use KON3 Potassium Nitrate
potassium nitrate (KNO3), also called saltpetre or nitre, an ionic white crystalline salt made up of potassium ions and nitrate ions. Uses of potassium nitrate include the manufacture of fertilizers, pesticides, glass, fireworks, explosives, and rocket fuels. It is also used as a food preservative, and when added to meat it causes a reaction between the myoglobin and hemoglobin in the blood, making the meat appear red in colour. It is also used as an additive in some toothpastes to help with tooth sensitivity. Potassium nitrate is toxic to humans in high levels, so its use is carefully controlled when human consumption is involved.
Potassium nitrate is an inorganic substance, commonly known as fire nitrate or soil nitrate, and KNO3 refers to the nitrate of potassium. It is colorless transparent orthorhombic crystal or rhombic crystal or white powder, odorless, non-toxic, salty and cool.
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. As fertilizer, it should be applied to vegetables, fruits and flowers, and some chlorine sensitive crops (such as potatoes, strawberries, beans, cabbage, lettuce, peanuts, carrots, onions, blueberries, tobacco, apricots, grapefruit and avocado).
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.
| No. | Paramets | Results |
|---|---|---|
| 1 | KNO3 | ≥99.4% |
| 2 | K2O | ≥46.4% |
| 3 | Nitrogen | ≥14.13% |

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.
