Influence Of Ph

In this paper Fe2O3 precursor coating on the surface of carbon balls was prepared by hydrothermal method using Fe(NO3)3·9H20 and glucose as the raw materials. After calcination Fe2O3 hollow sphere could be achieved. The influence of pH value on the preparation of hollow Fe2O3 spheres was studied using XRD and SEM respectively. The results show that the pH value has no effect on the formation of Fe2O3 phase, but has a giant influence on the morphology of the hollow spheres. The Fe2O3 hollow spheres were achieved when the pH value was between 3 and 7. The particles with sheet and block structure form when pH7. The mechanism was studied, When 3

The sphere aluminum hydroxide sulfate and hollow sphere boehmite were synthesized by using urea as precipitator with Al2(SO4)3•18H2O 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.
