| 产品介绍 |
应用 Chromium(III) potassium sulfate dodecahydrate (KCr(SO 4 ) 2 .12H 2 O) may be used for coating the slides for microscopic studies on Periplaneta americana . It may be used in the preparation of quasi-monodisperse spherical core-shell particles of Cr/α-Cr 2 O 3 . General Description Chromium(III) potassium sulfate dodecahydrate (Potassium chromium(III) sulfate dodecahydrate, Chrome alum) is a violet colored solid. It has been synthesized by reacting sulfur dioxide with potassium dichromate (diisolved in sulfuric acid) at -38°C. It is widely used chemical in dyeing and textile industry. Application Chromium(III) potassium sulfate dodecahydrate (KCr(SO 4 ) 2 .12H 2 O) may be used for coating the slides for microscopic studies on Periplaneta americana . It may be used in the preparation of quasi-monodisperse spherical core-shell particles of Cr/α-Cr 2 O 3 . |
