Hydrofluoric acid (HF)

Hydrofluoric acid.

Effect of hydrofluoric acid (HF) concentration to pores size diameter of silicon membrane.

This paper studies parameters which affect the pore size diameter of a silicon membrane. Electrochemical etching is performed in characterise the parameter involved in this process. The parameter has been studied is volume ratio of hydrofluoric acid (HF) and ethanol as an electrolyte aqueous for electrochemical etch. This electrolyte aqueous solution has been mixed between HF and ethanol with v...

However, HF is not only a strong corrosive, but also highly toxic towards higher concentrations: ...

Hydrofluoric Acid Exposure

A 21-year-old male was admitted to the emergency department with bleeding skin burns. He had been exposed to 70% hydrofluoric acid (HF) through his nitrile hand gloves during an etching glass procedure at work. He had painful lesions, which included bleeding skin abrasions due to seconddegree burns on the first and second fingertips on the right hand, and white spots on the left first finger, w...
