Because of its high activity, large surface area, strong adsorption and a series of excellent properties, nanometerγ-Al2O3 is widely used in structural ceramics, catalyst supports, porous filters and fluorescent materials and so on. However,γ-Al2O3 does not exist in nature, and particle size is too small that it is easy to aggregate. So how to prepare well dispersed, little aggregates, grain size controlled nano-y-Al2O3 is become a hot topic.
The influence of hydrolysis temperature, concentration of al...
