Hydrogen Fluoride

Formula: HF

Hydrogen Fluoride is a colorless, poisonous, liquefied gas.

Anhydrous hydrogen fluoride is used as a fluorinating agent in chemical reactions to produce fluorinated compounds. It is also used as a catalyst in isomerization, condensation, dehydration, polymerization and hydrolysis reactions. It is also used as the starting material to electrolytically produce fluorine gas.

It is also used to etch glass, producing frosted glass. And HF finds use in some chemical lasers. For semiconductor manufacturing, HF is used to etch silicon oxide.
