METHOD FOR PREPARING A MONOLITH MADE OF INORGANIC MATERIAL

摘要

The invention relates to a method for preparing a monolith made of inorganic solid foam. The method comprises a step for preparing a liquid/gas foam and a calcining step. During the preparation step, inert gas bubbles, which are saturated with organic solvent that cannot be mixed with water, are introduced into an aqueous solution, which contains a precursor of the inorganic material and contains a surfactant, through a sintered glass above which the precursor solution is placed. The foam, liquid/gas is optionally wetted with a constant delivery of aqueous precursor solution while adjusting the delivery of wetting according to the desired shape of the bubbles.
