Potassium nitrate is potassium nitrate, the experimental formula KNO? (potassium nitrate is an ionic compound, and has no molecule, so it has no molecular weight, only formula weight). The appearance is transparent, colorless or white powder, odorless, and its specific gravity (water = 1) is 2.11. The solubility in water is 13 g/100mL (depending on the temperature, the higher the temperature, the higher the solubility, among the chemical substances, the solubility of potassium nitrate is quite obvious). The deliquescence is lower than sodium nitrate, and it has a cooling stimulating salty taste. Soluble in water, slightly soluble in ethanol.

【Basic information】

【Use】

1. Used as analytical reagent and oxidant, and also used in the synthesis of potassium salt and the preparation of explosives.

2. It can be used as hair color agent, color protectant, antimicrobial agent, preservative in the food industry. For example, it can be used as a preservative in luncheon meat.

3. It is the raw material for making black powder, such as mine powder, fuse, firecracker, etc. Also used in fireworks to produce purple sparks. Mechanical heat treatment is used as a salt bath for quenching. The ceramic industry is used to make enamel paint. Used as a glass clarifier. Used in the manufacture of glass bulbs for automobile lamps, glass bulbs for optical glass kinescopes, etc. The pharmaceutical industry is used to produce penicillin potassium salt and rifampin drugs. Used to make cigarette paper. Used as a catalyst. Ore dressing agent. Used as compound fertilizer for crops and flowers.

4. Potassium nitrate is also a hair color agent allowed in China. It is reduced to potassium nitrite due to the action of bacteria in meat products to protect color and inhibit bacteria. China stipulates that it can be used for meat products, the maximum use amount is 0.5g/kg, and the residual amount shall not exceed 0.03g/kg.

5. Used to make fireworks, matches, ceramic glazes, fertilizers, etc.

6. Industrial potassium nitrate is also widely used in the manufacturing process of strengthened glass.
