Structural parameters of silica gels synthezid by the standard methods and by the method of rapid deposition have been studied. It has been shown that the proposed method of silica gel deposition allows to obtain homogeneously porous samples, including the mesoporous samples. It has been established that silicas obtained by the proposed method have a higher absorption capasity and a more narrow pore size distribution on effective radii. The new methods of hydroxide deposition opens wide opportunites for synthesis of adsorbents and catalysts with predetermined structure.
