产品说明

一般描述

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℃. It is widely used chemical in dyeing and textile industry.

应用

Chromium(III) potassium sulfate dodecahydrate (KCr(SO₄)₂.12H₂O) 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-Cr₂O₃.
