Al2O3 composite agent effects on phase transformation of nanometer TiO2 powder

Nano-composite TiO2 was synthesized via a liquid co-precipitation method using Al2O3 as heterogeneous composite agent. The products were characterized by differential scanning calorimetric analysis (DSC), X-ray diffractometer (XRD), and transmission electron microscopy (TEM), respectively. Effect of Al2O3 on phase transformation of TiO2 and the structure of composite were discussed.
