Application
Please enter the title here
Hydrogen fluoride (chemical formula HF) is an important industrial chemical, mainly used in semiconductor manufacturing, chemical catalysts, glass etching, metal processing and other fields. It is also widely used in fluoride synthesis, petroleum refining and pharmaceutical industries. ‌‌
Electronics and semiconductor manufacturing‌
Used for silicon wafer surface cleaning and oxide removal to ensure the quality of semiconductor devices. ‌‌
High-purity electronic grade hydrogen fluoride (99.999%) is used in wafer pickling and etching processes, often used in combination with nitric acid, hydrogen peroxide, etc. ‌‌
Industrial manufacturing‌
Glass etching: Dissolves silicon dioxide in glass through hydrofluoric acid, widely used in decorative glass and optical instrument processing. ‌‌
Metal smelting: Used for purification and surface treatment of metals such as aluminum and uranium, remove oxides and improve metal purity. ‌‌
Chemical synthesis‌
As a fluorinating agent and catalyst, it participates in the preparation of fluorides (such as aluminum fluoride, lithium fluoride) and fluorinated organics (such as polytetrafluoroethylene, refrigerants). ‌‌
Catalyze alkylation reactions in petroleum refining to improve oil quality. ‌‌
‌Other fields‌
Pharmaceutical industry: used as a fluorinated reagent to synthesize fluorinated drug intermediates. ‌‌
Laboratory analysis: used to prepare high-purity reagents and dissolve special materials. ‌‌
Characteristics and safety tips‌
Due to its strong corrosiveness and toxicity, hydrogen fluoride requires strict operating protection (such as wearing chemical protective clothing and goggles). Immediately rinse and seek medical attention after contact. ‌‌
