Application
Agriculture
Agricultural potassium nitrate is one of the important members of modern agricultural fertilizers, which overcomes the disadvantages of traditional fertilizers and is an ideal fertilizer for commercial crops such as tobacco, fruits and vegetables. It is a potassium and nitrogen compound fertilizer without chlorine, with good physical and chemical properties, the total content of potassium and nitrogen can reach 58%,. Application of agricultural potassium nitrate to a variety of crops has high fertilizer efficiency, easy to absorption, promoting seedling emergence and increasing yield. It plays an important role in improving crop quality.
Industry
1, used as analytical reagent and oxidant, and also for the synthesis and preparation of potassium salts.
2. In the food industry, they are used as chromogenic agents, color protecting agents, antimicrobials and preservatives, such as salted meat, to play an antiseptic role in luncheon meat.
3, it is the raw material for making black gunpowder, such as mine propellant, fuse and firecracker. It is also used for fireworks to produce purple sparks. Mechanical heat treatment is used as a quenched salt bath. Ceramic industry is used in the manufacture of enamel color drugs. Used as a glass clarifier. It is used for making automobile lamp glass shell, optical glass picture tube glass shell and so on. The pharmaceutical industry is used for the production of penicillin potassium salt, rifampicin. It is used for making cigarette paper. Used as a catalyst. Ore dressing agent. A compound fertilizer used as a crop and a flower.
4. Potassium nitrate is also the chromogenic agent permitted in China. It is reduced to potassium nitrite in meat products due to bacterial action, which plays a role in protecting color and bacteriostatic. China stipulates that it can be used for meat products. The maximum usage is 0.5g/kg, and the residue should not exceed 0.03g/kg.
5. It is used for making pyrotechnics, matches, ceramic glaze, fertilizer and so on.
6, industrial potassium nitrate is also widely used in strengthening glass manufacturing process.
