Investigation of effective parameters in the production of alumina gel through the sol-gel method

open access: yesCase Studies in Chemical and Environmental Engineering, 2023
Sol-gel chemistry is currently applied as one of the most widely used methods for synthesis of nanoparticles. In this method hydrolysis and poly-condensation reactions occur when the gel precursors are mixed with water and catalyst.
