Industrial Grade Potassium Nitrate, Purity 99.4% KNO3 for Agriculture Use
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.

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.
