Potassium fluoride is an inorganic salt, also known as potassium fluorine salt. It is a white monoclinic crystal or crystalline powder, with a salty taste, hygroscopic, and soluble in water. Its aqueous solution is alkaline and can corrode glass and ceramics. Therefore, it is commonly used for various glass etching, welding flux agents, wood preservatives, agricultural insecticides, pesticide intermediates, pharmaceutical raw materials, and organic fluorine materials. It plays an indispensable role in the construction, chemical, and agricultural industries.
Potassium fluoride is classified as a Class 6.1 hazardous substance, UN1812. It has a relative density of 2.454 and a melting point of 858℃. It reacts with acids to release highly corrosive and irritating hydrofluoric acid, which can corrode glass. This substance is toxic, with an LD50 of 245 mg/kg, and is irritating to the skin and mucous membranes of the eyes. Operators must wear protective equipment when handling it.
Potassium fluoride can be exported by sea either as LCL or in FCL. Therefore, it is commonly used for various glass etching, welding flux agents, wood preservatives, agricultural insecticides, pesticide intermediates, pharmaceutical raw materials, and organic fluorine materials, playing an indispensable role in the construction, chemical, and agricultural industries.
Applications of Potassium Fluoride:
Used for glass engraving, food preservation, and electroplating;
Can be used as a welding flux agent, insecticide, catalyst, and absorbent (to absorb HF and moisture), etc.;
Used as an analytical reagent and complexing agent. It is also a raw material for the production of potassium hydrogen fluoride;
Can be used as a fluorinating agent for organic compounds.
Hazards of Potassium Fluoride:
Health Hazards: This substance causes significant damage to mucous membranes, upper respiratory tract, eye, and skin tissues. Inhalation can lead to inflammation, edema, and spasms of the throat and bronchi, chemical pneumonia, and pulmonary edema, which can be fatal. Symptoms of poisoning include a burning sensation, cough, wheezing, laryngitis, shortness of breath, headache, nausea, and vomiting.
Fire and Explosion Hazards: This substance is non-combustible, toxic, and irritating, causing severe damage to mucous membranes, the upper respiratory tract, eyes, and skin.
In maritime export, potassium fluoride is classified as a Class 6.1 hazardous substance, with UN1812, and can be packaged in either Category II or III packaging. In maritime export, potassium fluoride is often packed in bags.
