Hydrofluoric acid (HF) is a highly corrosive and toxic chemical compound composed of hydrogen and fluorine. It is an aqueous solution of hydrogen fluoride and is widely used in industrial applications due to its unique properties. Hydrofluoric acid can dissolve many materials, including silica and glass, making it valuable in etching and cleaning processes in electronics and semiconductor manufacturing.

Hydrofluoric acid-based solutions are often employed for their ability to selectively etch glass, quartz, and silicones, owing to their capability to break silicon-oxygen bonds. This property allows precise material removal in microfabrication, circuit board production, and gemstone etching. In addition to etching, HF is used in the production of fluorinated compounds, including refrigerants, pharmaceuticals, and advanced polymers.

The handling and use of hydrofluoric acid require strict safety measures because it can penetrate tissues rapidly, causing severe burns, deep tissue damage, and systemic toxicity. Exposure to even small quantities can be hazardous, necessitating the use of specialized protective equipment and protocols. Hydrofluoric acid reacts with calcium in the body, which can lead to hypocalcemia and potentially fatal outcomes if not promptly treated.

Due to its hazardous nature, alternatives are often sought in various applications, but HF remains essential in industries demanding its unique reactivity. Its use is regulated in many countries, and proper disposal methods are critical to prevent environmental contamination. Overall, hydrofluoric acid-based solutions are integral in certain high-tech manufacturing processes but pose significant safety and environmental challenges that require careful management.
