- •
RSM is a useful tool to optimize the process variables of synthesis of B-Al2O3 by sol-gel method.
- •
Presence of tetraborate ion in hydrolysis cause the formation of nano-spheres.
- •
Increase in the number of substituted tetraborate ion leads smaller nano-spheres.
- •
Agglomerate size is controllable in condensation step.
- •
High hydrolysis ratio results uniform and narrow mesoporous structure with interpore formation.
