What is a Hydrogen Fluoride (HF)?

Hydrogen fluoride is an inorganic compound composed of hydrogen (H) and fluorine (F), existing as a colorless gas or pungent liquid at room temperature. When dissolved in water, it forms hydrofluoric acid, a highly corrosive solution capable of dissolving glass, metals, and quartz. This unique property makes HF indispensable in industries such as glass etching and semiconductor manufacturing.

In chemical industries, HF is a key precursor in the production of fluorine-containing compounds, including refrigerants, PTFE (Teflon), pharmaceuticals, and agrochemicals. Its reactivity allows it to participate in a wide range of synthetic processes. Despite its utility, hydrogen fluoride is extremely hazardous. It can cause severe chemical burns and deep tissue damage upon skin contact, even if symptoms appear minor initially. Inhalation or ingestion may be fatal. Strict handling protocols, including protective equipment and proper ventilation, are mandatory. Emergency treatment often involves calcium gluconate to counteract fluoride ion toxicity.
