About Hydrofluoric Acid 49% Solution, Electronic/Cleanroom Grade

Hydrofluoric acid, HF, is the aqueous solution of Hydrogen Fluoride. Fluorine is the only halogen that does not form a strong acid, due in part to the electronegativity and small size of the fluorine atom which results in stronger bond formation between fluorine and hydrogen. Lab Alley’s Hydrofluoric Acid, 49% Solution, Electronic/Cleanroom Grade contains 49% Hydrofluoric Acid mixed with a balanced quantity of Water. It is specially produced for the electronic industry to perform cleaning of silicon wafers and etching of semiconductors, as these delicate applications require ultra-purified solvents.

Common Uses and Applications

  • Cleaning of silicon wafers
  • Etching of semiconductors
  • Laboratory reagent
