Use:
Due to the ability of hydrofluoric acid to dissolve the oxide, it in the purification of aluminium and uranium plays an important role.
Hydrofluoric acid is also used to etch glass, can be carved patterns, mark scale and text; Oxide on the surface of the semiconductor industry to use it to remove silicon, it can be used for isobutane and butane in refinery alkylation reaction catalyst, removal of oxygen impurity on the surface of the stainless steel in the process of "acid" is also using hydrofluoric acid.
Hydrofluoric acid is also used in a variety of synthesis of fluorinated organic matter, such as Teflon (ptfe) and refrigerant freon.
