摘　　要：通过控制酸性环境、添加表面活性剂、加入纳米SiO2粒子和引入超声波场，利用盐析结晶方式制备了粒度较为均匀的NaCl微粒，粒径范围为1-11μm。采用SEM、XRD对NaCl微粒进行了表征，结果表明微粒具有完好的立方体晶体特征和NaCl特征峰。根据实验结果分析了NaCl微粒结晶粒子的形成机理。By means of adding surfactant, controlling the pH value and introducing the ultrasonic wave field, the NaCl particles were prepared. The particles perform uniformity granularity with the granularity scope ranging from 1 to 11μm. The product was characterized by SEM and XRD. The results show that the particles appear cubic crystal outline and sodium chloride characteristic band.
