Thearticlepresentsexperimentaldataconfirmingtheeffectof capillary active substance (surfactants) and sedimentation stability on the final structure of the gel with stabilized silicic acid. Studies of the macrostructure of silica gel depending on the method of emulsifi ation of silicic acid sol and the effect of the resulting fractality on the strength of the mold are presented. Thedirectionof modifying the binder for lost‑wax casting (LWC) with obtaining the specified properties of the ceramic shell is shown. Thecomplexeffectof organic polymers on the sol – gel system has been established. The conclusion is made about the possibility of using an aqueous dispersion of acrylic to form a given structure of a silica gel.
