  • Production of alumina ScienceDirect

    Jan 01, 2011· The process of calcination initially involves proton captured by an adjacent hydroxyl, resulting in a water molecule which subsequently diffuses out of the structure. Complete calcination, involving the removal of all the hydroxyls and conversion to alpha alumina, is thus difficult and requires extended times at temperatures above 1000 °C.Optimisation of SBA-15 properties using Soxhlet solvent,Nov 01, 2016· The extraction process removed part of template, then the decrease of template in the pores material redounded to increase the pores since, because the calcination process is less aggressive.
