应用：显微分析用固着剂，皮革，制备其他铬盐。

运输条件：常规运输

产品介绍：易风化。在透射光下呈宝石红色，加热到100oC失去部分结晶水而变绿色，110℃时得二水物，350℃时变成无水物呈浅黄绿色，并失去水溶性。溶于水和稀酸，不溶于醇，能溶于4份冷水、2份沸水，几乎不溶于醇。其水溶液冷时呈紫色，热时呈绿色。显微分析用固着剂，皮革，制备其他铬盐。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.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.
