Process for the preparation of materials based on inorganic oxides with a size of monodisperse particles and resulting materials.

摘要

PRESENTS A METHOD TO PREPARE MATERIALS BASED OXIDES OR Inorganic Oxides spherically with a distribution SUBSTANTIALLY monomodal which consists of the formation of a colloidal suspension of at least one of the oxides INORGANIC INTERESTING, THE ADDITION TO THIS COLLOIDAL SUSPENSION OF A SOLVENTE immiscible colloidal suspension, FINA scattering two-phase mixture obtained from a dispersion of the same diameter, thickening of the particles BY COALESCENCE LIMITED TO THE DIAMETER DESIRED, gelation said mixture by adding A SECOND sOLVENT CONTAINING A gelling agent, and removal of the solvent.
