Potassium fluoride ( FK )/CAS:7789-23-3
BRIEF DESCRIPTION
Potassium fluoride is an inorganic compound that appears as a white crystalline solid and melts to extremely low temperatures. It is composed of a compound of metal ions potassium and fluorine and is highly corrosive. It has strong resistance to metal corrosion and can be used to prepare organic solvents and lubricants. It can also be used as a corrosion inhibitor and has a wide range of uses.

USE
(1) Pharmaceutical industry: Potassium fluoride is used as a raw material for antibacterial drugs to treat respiratory infections, eye diseases, etc.
(2) Agricultural industry: Potassium fluoride is used to make pesticides to eliminate pests and as an antibacterial agent for crops and bacteria.
(3) Industrial industry: Potassium fluoride can be used in glass engraving, food preservation, electroplating, pharmaceutical preparation, additives, lighting fluorescent lamps, welding fluxes, smelting metals, metallurgy, fluorinating agents for organic compounds, catalysts, absorbents (absorbing HF and moisture) and grinding paste, etc., are also raw materials for preparing potassium hydrogen fluoride.
(4) Laboratory: Multifunctional fluoride ion source used to study ion-specific swelling and deswelling of amphoteric polymer gels. Room temperature oxidation of noble metals in hydrogen fluoride, and measurement of the electronic polarizability of ions in alkali metal halide polymers.
STORAGE CONDITIONS
1. Store in a cool, ventilated warehouse.
2. Keep away from fire and heat sources.
3. Store in a sealed container and keep away from children.
4. It should be stored separately from acids to prevent it from reacting with acidic substances.
5. Store separately from food chemicals, avoid mixed storage.
6. The storage area should be equipped with suitable materials to contain leaks.
7. Hydrofluoric acid corrosive gas will be produced when it comes in contact with water, so be careful to prevent moisture and moisture.
8. Potassium fluoride is corrosive, so care should be taken to avoid contact with skin, eyes and mucous membranes.
9. Wear protective glasses, gloves and protective clothing when operating.
PACKAGE
1. Plastic woven bags, aluminum foil bags, cardboard barrels.
2. Other forms of packaging according to customer needs.
CHEMICAL PROPERTIES
1. Potassium fluoride comes in various forms. It can be in the form of powder or crystal. It has a smooth surface and is easily oxidized into potassium fluorocyanate when exposed to air.
2. Potassium fluoride has certain toxicity, so handle it with caution. If it accidentally comes into contact with your eyes or skin, wash it immediately with plenty of water.
3. The solubility of potassium fluoride is related to temperature. The higher the temperature, the higher the solubility.
4. Potassium fluoride has strong resistance to metal corrosion and can be used as coating to protect metal surfaces.
5. Potassium fluoride has strong surface activity and can be used to prepare organic solvents and lubricants, and can also be used as a corrosion inhibitor.
6. Potassium fluoride easily combines with acidic substances to produce fluorocyanide, which can cause irritation or even burns when it comes into contact with the eyes, skin or mouth.
