摘要：
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.
