DESCRIPTION

Industrial potassium nitrate

Molecular formula: KNO3

English name: Potassium Nitrate

CAS No.： 7757-79-1

Molecular weight: 101.1

Property: Colorless transparent prismatic or white particles or crystalline powder. Slightly hygroscopic, easily soluble in water, absorbs heat when dissolved in water, and lowers the temperature of the solution. Insoluble in anhydrous ethanol and ether. Under acidic conditions, it has oxidizing properties and decomposes into oxygen upon heating. Friction or impact with organic matter, sulfur, phosphorus, etc. can cause combustion or explosion.

Usage: Used as raw material for fireworks, ignition lines, and firecrackers; Penicillin potassium salt, rifampicin and other drugs; Cigarette paper, catalysts, and mineral processing agents; Ceramic glaze color; Hair colorants and preservatives.

Agricultural potassium nitrate

Properties: White powder or granular, containing 13.5% nitrate nitrogen (N) and 46% K2O. Agricultural potassium nitrate is a high-quality nitrogen potassium binary compound fertilizer. All dissolved in water.

Product features:

(1) Increased yield: Provides sufficient potassium fertilizer for crop growth, significantly improving crop photosynthesis and yield.

(2) Improving quality: It can make the fruit colorful, expand quickly, have a positive shape, increase the sugar content of the fruit, and have a pure and sweet taste.

(3) Enhance disease resistance: It is best to use stress resistant fertilizers to improve the crop's ability to resist diseases, pests, drought, and salt damage.

Usage: Widely used in various vegetables, fruits, economic crops, and grain crops, it can be used as base fertilizer, topdressing, foliar fertilizer, soilless cultivation, etc.

Potassium nitrate for optical glass

Property: Colorless transparent prismatic or white particles or crystalline powder. Slightly hygroscopic, with lower hygroscopicity than sodium nitrate, easily soluble in water, absorbs heat when dissolved in water, and lowers the temperature of the solution. Insoluble in anhydrous ethanol and ether. Under acidic conditions, it has oxidizing properties and decomposes into oxygen upon heating. Friction or impact with organic matter, sulfur, phosphorus, etc. can cause combustion or explosion.

Usage: Used as a glass clarifying agent, in the manufacture of automotive lamp glass, optical glass, cathode ray tube glass shells, clock glass, mobile phones, and computer touch screens.
