Application

Chromium(III) potassium sulfate dodecahydrate [KCr(SO4)2.12H2O] has been used for the dissolution of gelatin in various studies.It may be used as a starting material in the synthesis of quasi-monodisperse spherical core-shell particles of Cr/α-Cr2O3 to be used as solar absorbers.

General description

Chromium(III) potassium sulfate dodecahydrate (Potassium chromium(III) sulfate dodecahydrate, Chrome alum) is widely used chemical in dyeing and textile industry. It can be synthesized by reacting sulfur dioxide with potassium dichromate (dissolved in sulfuric acid) at -38°C.
