摘　　要：本文研究以In和HCl为原料、以正丁醇BuOH作为有机溶剂,采用微波干燥法制备高纯无水InCl3的工艺技术。传统方法制备高纯无水InCl3对温度控制要求较为严格,存在着设备复杂、产量低、后处理难及环境污染严重等缺点。本文研究的利用微波干燥法制备高纯无水InCl3粉体的工艺,具有热利用率高、加热均匀、易控制、加热时间短、选择性加热等特点,因而具有重要应用价值。In this paper, the preparation process of high purity anhydrous InCl3 with the InCl3·4H2O as raw material and the BuOH as organic solvent is studied. As to the traditional preparation methods, there are many shortcomings such as stringent temperature control, complicated equipment, low yields, difficult aftertreatment, serious environment pollution and so on. The preparation process of high purity anhydrous InCl3 by microwave drying method studied in this paper has a series of advantages, thus having great application value.
