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。 |

Abstract: |
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. Finally, the growth mechanism of the ultrafine sodium chloride particles was studied. |
Keywords: sodium chloride crystal dispersion ultrafine particles |
