perchloric acid

Perchloric acid --HCLO4 CAS: 7601-90-3 Colorless and clear liquid.Relative density 1.764, melting point - 112°C, boiling point 39°C(7466.032Pa), approximately 90°C when starts to decompose. Dissolves in the water, its water-soluble fluid has the very good electrical conductivity. Is the strong acid, also is the strong oxidant, has the strong corrosiveness. Used as highly purified electronic chemicals and etching agent, useful in galvanizing industry, the film strip, the artificial diamond industry, the electricity polishing industry and the pharmaceutical industry, semiconductor,also useful in producing the grinding wheel except the carbon granule impurity.Serves as the strong oxidant, but also uses in producing the fireworks and the blasting explosive.
