| Abstract: | A process of coating Al2O3 particles with TiO2 by hydrolysis of Ti(OC4H9)4 using chemical vapor deposition in a rotary reactor has been developed. The process resulted in (1) a coating film of TiO2 which was compact and uniform with the fraction of TiO2 being 0.1%–10.0% and (2) an amorphous TiO2 coating at a low reaction temperature converted to anatase at a reaction temperature higher than 673 K. |
