Products Description
Hydrofluoric acid, an inorganic compound with the chemical formula HF, is normally a colorless, poisonous gas with an irritating odor, is highly hygroscopic, produces white smoke when in contact with the air, is easily soluble in water, and is infinitely miscible with water to form hydrofluoric acid. Hydrofluoric acid molecules have hydrogen bonding, will show some abnormal properties, such as boiling point is much higher than other hydrogen halides. Hydrofluoric acid is chemically reactive and can react with many compounds. It as a solute present in water is a weak acid, while pure hydrogen fluoride is a strong acid.
Use
It is used in the cleaning and corrosion of integrated circuits (IC) and very large-scale integrated circuits (VLSI) chips, and is one of the key basic chemical materials in the production process of microelectronics industry, and can also be used as analytical reagents and preparation of high-purity fluorine-containing chemicals.
