    Hydrofluoric acid (HFA) is the inorganic acid of elemental fluorine HFA is used in fluorocarbons, fluoropolymers, aluminum production, stainless steel pickling, uranium processing, glass etching, oil well acidizing, gasoline production, removal of sand and scale from foundry castings, and as a laboratory reagent
  • Hydrofluoric Acid - an overview | ScienceDirect Topics
    Hydrofluoric acid (HF) is a dangerous inorganic acid that is used widely in the chemical industries, electronics manufacturing, glass etching, smelting, cleaning, and other industrial fields [1–3] It exists in two forms: in a purified form (>99%), called anhydrous hydrofluoric acid, and in a dilute form, called aqueous hydrofluoric acid [4]

  • Hydrofluoric acid burns - ScienceDirect
    The concentration of hydrofluoric acid in individual cases varied from 1 to 98% with 38 5% of cases involving solutions with a concentration of ≤1% hydrofluoric acid There were six cases in which the concentration of hydrofluoric acid was ≥50% and in all of these cases the method of contact was work related involving refinery workers
  • A review of hydrofluoric acid and its use in the car wash industry
    Hydrofluoric acid (HF) is a valued chemical in the academic, domestic, and industrial settings, being a precursor to numerous products and materials [1] Large quantities of crude HF were first prepared by Carl Wilhelm Scheele in 1771 [2] In the late 1800s and early 1900s, HF was utilized for glass etching, foundry scale removal, and sodium
