Chemical formula: HF See also: Chemical Table.
The only acid that will dissolve glass. Neat, it leaves a clear finish; in conjunction with sulphuric acid, it produces a high gloss finish used in polishing lead glass; in mixture with ammonia, it produces frosting
a poisonous solution of hydrogen fluoride gas in water. This colorless, fuming liquid is extremely corrosive and will etch glass. Hydrofluoric acid is used to etch silicon dioxide and, when combined with other acids, silicon.
A strong acid used to remove silicon dioxide. Generally it is mixed with ammonium fluoride for better etch-rate control.
H6F6, H4F4, H2F2 or HF dependent on temperatures, the reaction of sulfuric acid with solid fluorides, corrosive, used in etching glass.
a weak poisonous liquid acid; formed by solution of hydrogen fluoride in water
a colorless, highly corrosive acid that attacks all silicates; used to etch the surfaces of glass and porcelain.
A highly corrosive acid that attacks silicates such as glass. Pure hydrofluoric acid dissolves glass, leaving a brilliant, acid-polished surface.
An aqueous solution of hydrogen fluoride that is a weak poisonous acid that attacks silica and silicates, used for finishing and etching glass.
An acid (in various dilutions) commonly used to etch oxide in many MEMS fabrication processes, such as sacrificial oxide release process.
chemical formula HF, hydrofluoric acid a relatively strong acid mainly used to etch silicon dioxide. Hydrofluoric acid is commonly sold as a 49% solution and has a density of 1.17Kg/L. Fluorine is not only toxic but may be absorbed through the skin without immediate evidence of irritation and later react with the calcium in bones and or poison the person exposed to the chemical.
The only material that attacks silica (a basic constituent of glass). It is used for etching.
Hydrofluoric acid is a highly toxic and corrosive solution of hydrogen fluoride in water. Gaseous hydrogen fluoride is sometimes called anhydrous hydrofluoric acid.
