Like everything destined for the semiconductor fab plant, the hydrofluoric acid used for etching silicon wafers has to be as close to contaminant-free as possible. Electronics-grade hydrofluoric ...

"Until now, hydrofluoric acid was used to etch away the aluminum in the MAX, which then resulted in a system of atomically thin layers that can slide against each other with very little resistance.

Hackaday editors Elliot Williams and Mike Szczys marvel at the dangerous projects on display this week, including glass etching with hydrofluoric acid and pumping 200,000 A into a 5,000 A fuse.

Hydrofluoric acid (HF) and Hydrogen Fluoride (HF) are very poisonous, highly irritating and corrosive. Hydrofluoric acid or Hydrogen Fluoride (HF) is fatal if inhaled, if swallowed, or in contact with ...
