Effect of precursor pH on the formation characteristics of sol-gel mullite

Mullite precursor gel of stoichiometric composition 3Al 2O 3 · 2SiO 2 has been prepared by reacting boehmite sol and tetraethyl orthosilicate (TEOS) in a stoichiometric ratio. The pH of the preparation medium was varied from pH 3.5–8. The sol to gel transformation of the precursor was studied using...
