7789-23-3 Usage

Physical and Chemical Properties

Potassium fluoride is basis raw material of manufacturing fluoride, chemical formula is KF. Molecular weight is 58.10. It is colorless cubic crystal or white powder. It is poisonous! It is deliquescent. Taste is salty. Specific gravity is 2.48. Melting point is 858℃. Boiling point is 1505℃. It is soluble in water. It was dissolved in hydrofluoric acid and ammonia. It is insoluble in ethanol, acetone. Aqueous solution is alkaline and it can corrode glass and porcelain. It can cause irritation for human skin, mucous membrane and eye. When belows 40.2℃, it can crystallize in an aqueous solution to give dihydrate KF·2H2O, which is monoclinic, it is self-dissolved crystalline water at 41℃. It can be obtained by the thermal decomposition of potassium hydrogen fluoride or potassium carbonate (or potassium hydroxide) and hydrofluoric acid (40% or anhydrous). It can be used for glass engraving, food preservation, it can be also used as welding flux, fluoride, pesticides,etc.

Health Hazard

TOXIC; inhalation, ingestion or skin contact with material may cause severe injury or death. Contact with molten substance may cause severe burns to skin and eyes. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.


Industry Application Role/benefit
Organic synthesis Preparation of various organic fluoride Fluorinating agent/replaces other halide ions like chlorine, bromine etc.
Chemical manufacture Manufacture of polyurethanes and alkyl benzenes Catalyst/promote the reaction rate
Manufacture of pesticides and insecticides Fluorinating agent; ingredient
Manufacture of potassium bifluoride Raw material
Metallurgy Soldering Soldering fluxes/help to remove oxide film
Tin plating Plating composition/source of fluoride
Glass Etching of glass Glass etching composition; source of fluoride
Others Food and wood preservative Source of fluoride
Absorption of hf and moisture Adsorbent/anhydrous potassium fluoride has hydroscopicity
Complexometric titration of tantalum Masking agent
Extraction of tantalum from ore Precipitator/reacts with fluorotantalic acid to precipitate potassium fluorotantalate

Reactivity Profile

Potassium fluoride reacts with acids to evolve corrosive and toxic hydrogen fluoride. Aqueous solutions corrode glass and consequently are prepared and stored in polyethylene containers. The pure solid may be stored in glass containers. Reacts violently with (Pt + BrF3). [NTP 1992].

Fire Hazard

Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Some are oxidizers and may ignite combustibles (wood, paper, oil, clothing, etc.). Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated.

Chemical Properties

Potassium fluoride, KF, is a colorless, deliquescent crystalline solid that has a melting point of 846 °C(1550 °F). Potassium fluoride has a salty taste and is poisonous. It is soluble in water,but insoluble in alcohol. Potassium fluoride is used in etching glass,preservatives, and insecticides.
