摘　　要：本实验采用铝屑、硫酸钾等制备硫酸铝钾晶体,所得产率为63.4%,并采用扫描电镜对硫酸铝钾晶体形貌结构进行表征分析。结果表明:加入晶种后,硫酸铝钾逐渐长成均匀的球形结构;采用无水乙醇对硫酸铝钾晶体进行洗涤,随着硫酸铝钾浓度的增大,球形结构逐渐被破坏,变成无规则的多边形。This test is for the preparation of potassium aluminium sulfate crystal adopting aluminum scraps, potassium sulfate and other materials, getting the productive rate of 63.4%, and characterizes the morphologic structure of potassium aluminium sulfate crystals wit scanning electron microscopy（SEM）, the results of which show that potassium aluminium sulfate has gradually grown into homogeneous spherical structure after adding the seed crystal, and the spherical structures is destroyed gradually and turned into unconstant polygon along with the increase of the concentration of potassium aluminum sulfate when adopting anhydrous ethanol for washing potassium aluminium sulfate crystal.
