The core-shell structures synthesis process by one-step hydrothermal method has remarkable peculiarities,such as simple procedures and short production cycles.In order to get the precursor with the core-shell structure,its important to study the technological parameters.In this paper,the pH value,the concentration of AlCl3,the mass ratio of core and shell,the hydrothermal temperature and time were detailed discussed.In order to get well-coated core-shell material,the technological parameters were the pH value=8.5-9.8,the concentration of AlCl3 0.040-0.050g/ml,Al2O3∶TiO2=10 %-28.5 %,the hydrothermal temperature 200℃ and the hydrothermal time 3 hours.
