Description: Potassium nitrate is an inorganic substance, colorless transparent rhombic crystal or rhombic crystal or white powder, odorless, non-toxic, salty and cool. Moisture absorption in the air is small, not easy to caking. Potassium nitrate is a chlorine-free potassium compound fertilizer with high solubility, and its effective components nitrogen and potassium can be quickly absorbed by crops without chemical residue. As fertilizer, 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 avocado, etc.). Potassium nitrate is a strong oxidant and can cause combustion and explosion in contact with organic matter. Therefore, potassium nitrate should be stored in a cool and dry place, away from fire, heat source. Do not mix with reducing agent, acid, combustible and metal powder. Application: 1. Potassium nitrate can be used as fertilizer and is commonly used in vegetables, fruits and flowers, as well as some chlorine-sensitive crops. Fertilizer can also be made for crops and flowers. 2. Potassium nitrate can be used as an analytical reagent and oxidant as well as in the synthesis of potassium salt. 3. Used in the food industry as a hair colorant, coloring agent, antimicrobial agent, preservative, e.g. for cured meats, as a preservative in luncheon meats. But there are specific dosage rules. 4. Potassium nitrate can be used to make black powder, such as mine powder, ignition wire, firecracker raw material. Also used in fireworks to produce purple sparks. 5. Mechanical heat treatment of potassium nitrate can be used as a quenching salt bath. 6. Used in the pharmaceutical industry for the production of your penicillin potassium, rifampicin. 7. Industrial potassium nitrate is also widely used in the production process of reinforced glass. For example, it is used as glass clarifier, automobile lamp glass case, optical glass picture tube glass case, etc.NPK Fertilizer factory website:http://www.junchi-chemical.com/npk-fertilizer/
