Potassium fluoride dihydrate is widely used in the field of metallurgy as a flux for soldering and welding, particularly for aluminum and its alloys. It helps in the removal of oxides from metal surfaces, ensuring stronger and cleaner joints. In the glass industry, it is employed as an additive to improve the clarity and durability of glass products. Additionally, it serves as a fluorinating agent in organic synthesis, facilitating the introduction of fluorine atoms into various compounds. It is also utilized in the production of specialty chemicals and as a preservative in wood treatment to prevent fungal decay. In analytical chemistry, it acts as a reagent for specific tests and measurements.
