A process is provided for preparing an inorganic material in the form of an alveolar monolith of a silica matrix where the monolith includes interconnected macropores. The process includes at least one step of mineralizing an oil-in-water emulsion formed from droplets of an oily phase dispersed in a continuous aqueous phase and in which colloidal solid particles are present at the interface formed between the continuous aqueous phase and the dispersed droplets of oily phase. Such materials obtained according to this process may be used, especially for separative chemistry and filtration, for performing chemical reactions catalyzed in heterogeneous phase, as thermal or phonic insulators, or as templates for manufacturing controlled-porosity carbon skeletons.

Process for preparing cellular inorganic monolithic materials and uses of these materials

A material in the form of solid particles with a diameter varying from 10 &#x3bc;m to 1 cm is provided, composed of a continuous solid shell having at least one silicon oxide, said shell imprisoning an aqueous phase The aqueous phase includes at least one hydrophilic substance of interest Sand at least one droplet of a fatty phase predominantly having a crystallizable oil in the solid state at the storage temperature of said material The crystallizable oil has a melting point (T) of less than 100&#xb0; C. and including at least one lipophilic substance of interest S.
