Abstract

Article PreviewArticle PreviewThe purpose of this work was to investigate the mechanism of macroporous zirconia particles formation by hydrothermal synthesis. Hydrothermal synthesis of zirconia was prepared from precursor solution of Zr (NO 3) 2 with a concentration of 0.3 M at temperatures of 300 and 200 C carried out in a batch and a continuous reactor, respectively. Hydrothermally synthesized colloid subsequently was mixed with polystyrene template to form macroporous zirconia particles, and then was synthesized hydrothermally for 1 hour at temperature of 150 C and 200 C. Once the synthesis was complete, the particles were then dried at temperature of 60 C for 6 hours. In order to eliminate polystyrene template from the particles, the dried particles were calcined at temperature of 600 C and 900 C for 6 hours. The morphology of particles formed were characterized by scanning electron microscope (SEM …
