A method of synthesis of crack-free titania membranes has been investigated. The most important parameters studied were the variation of agglomerate sizes in the liquid phase as a function of the synthesis conditions of the sol, as well as the structural development of the titania membrane during thermal treatment. Characterization of the structure has been performed by measuring the change in the pore size and surface area and by investigating the composition of the titania phases. A correlation has been found between the synthesis of the sol, the agglomerate size in the sol and the structure development after thermal treatment of the membrane top layers.
