Abstract

LE PROCEDE POUR LA PREPARATION D'UN CORPS POREUX COMPREND LA FORMATION D'UN GEL HUMIDE DE SILICE CONCENTRE, CONTENANT UN ELEMENT D'ADDITION, PAR HYDROLYSE, PUIS LE SECHAGE DU GEL HUMIDE POUR OBTENIR UN GEL SEC, UNE SOLUTION AQUEUSE POUR DILUTION OBTENUE EN MELANGEANT UN SOLVANT TEL QU'UN ALCOOL ET DE L'EAU POUR L'HYDROLYSE, EST UTILISEE A CET EFFET A LA PLACE DE L'EAU PURE. UTILISATION DE CE PROCEDE POUR OBTENIR UN GEL HOMOGENE ET TRANSPARENT.THE PROCESS FOR THE PREPARATION OF A POROUS BODY INCLUDES FORMING A WET GEL OF CONCENTRATED SILICA, CONTAINING AN ADDITIONAL ELEMENT, BY HYDROLYSIS, THEN DRYING THE WET GEL TO OBTAIN A DRY GEL, AN WATER-BASED SOLUTION FOR DILUTION OBTAINED BY MIXING A SOLVENT SUCH AS AN ALCOHOL AND WATER FOR HYDROLYSIS, IS USED FOR THIS EFFECT IN PLACE OF PURE WATER. USE OF THIS PROCESS TO OBTAIN A HOMOGENOUS AND TRANSPARENT GEL.
