Abstract
Ceria stabilized zirconia microspheres of about 150 microns were prepared by external gelation. The effect of vibration frequency on jet droplet dispersion and size uniformity was investigated. The diameter variances of microspheres prepared at frequency range of 1300 to 2300 Hz were calculated. The optimal frequency was found to be in good accordance with Raleigh’s theory. The obtained microspheres under optimal frequency were characterized by optical microscopy, scanning electron microscopy (SEM) and X-ray diffraction (XRD). The data showed their good size uniformity, smooth surface, compactness, and good CSZ phase.
