摘要：

The sphere aluminum hydroxide sulfate and hollow sphere boehmite were synthesized by ousing urea as precipitator with Al-2(SO4)(3)center dot 18H(2)O as precursor via a hydrothermal method. The effects of hydrothermal temperature on micromorphology were studied. Results showed that sphere aluminum hydroxide sulfate could obtain on lower temperature. As the hydrothermal temperature increased, sphere aluminum hydroxide sulfate begin to dissolve in situ and recrystallize. In the end, hollow sphere boehmite assembled by flake was formed.
