| 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. |
