Abstract

The objective of this study has been to compare conventional and microwave hydrothermal treatment of TiOCl2 solutions. Colloidal titania sospensions have been prepared by forced hydrolysis at 195°C for different time ranging from 1 to 32 h for the conventional synthesis and from 5min to 1h for the microwave ones. The effect of the microwave technology on both the synthesis conditions and titania nanoparticles properties have been evaluated. Particles morphology and crystallinity have been studied by using transmission electron microscopy (TEM) and X-ray diffraction (XRD). The thermal and chemical stability of the obtained powders have been determined by TG/DTA analysis.
