The process of Chemical Vapor Deposition (CVD) coating was investigated in the rotating reactor. Base on this ,TiO2 was coated on A12O3 particles by using hydrolysis reaction of Ti(OC4H9)4, and the mechanism of the coating process was studied.

• 探讨了回转炉化学气相淀积（CVD）包覆新工艺,利用Ti（OC_4H_9）_4水解,在Al_2O_3粒子表面实现了TiO_2包覆,研究了包覆过程特征。
