Abstract: The effects of temperature and pressure on the preparation of Al2O3 coated TiO2 nanocrystals as well as its antiflocculation were investigated in this paper. The experimental result reveals that the coating process has greatly improved the antiflocculation of TiO2 nanocrystals in the solvent of ethanol, however, temperature and pressure have little different effect on it.
