FIELD: chemistry. ^ SUBSTANCE: invention relates to area of obtaining highly pure silica gel. Method of obtaining silica gel from aerosyl and distillated water is based on sol - gel process, in which gelatinisation is takes place on porous ceramic bottom layer with combination of methods of micro filtration and capillary phase separation. ^ EFFECT: method allows obtaining silica gel of high degree of purity (content of admixtures (Fe, Al, Na) - 0,0001-0,0003%) without using additional regents. ^ 1 ex |
