| Abstract: Nanophase TiO2-Al2O3 composite particles synthesized by gas phase oxidation of TiCl4 and AlCl3 in an aerosol reactor were characterized by EDS, XPS, TG-DTA, TEM, XRD and BET surface area analysis. The results showed that the morphological structure of the composite particles were influenced by AlCl3 feed ratio and reaction temperature. When Xinlet=2.80 and T=1400℃, the composite particles were mainly composed of rutile TiO2,α Al2O3, and Al2TiO5, the average particle size was 25.3 nm and GSD (Geometric tandaed Squace Deviation) was 1.51. Other processing parameters affecting the particle size was also analyzed. |
