Aplicaciones

Perchloric acid is used as a precursor for ammonium perchlorate, which is used in rocket fuel. It is useful for etching of liquid crystal displays, etching of chrome, ore extraction and in analytical chemistry. It is used as a strong oxidizer and as a solvent for metals and alloys. It serves as a deproteinization reagent in food analysis. As a dehydrating agent, it is used for the determination of silica in iron and steel and in cement and other silicate materials. It is involved in the separation and determination of copper and other metals and alkali metals such as sodium and potassium. It is also used as an adjunct to increase the reduction potential of cerate salts in volumetric analysis. It finds application in the computer industry for etching liquid crystal displays in critical electronic applications.

Notas

Hygroscopic. Incompatible with strong bases, strong acids, amines, phosphorus halides, alcohols, organic materials, powdered metals and strong reducing agents.
