Abstrakt: Hydrargillite crystals were synthesized within the pores of a porous membrane (porous glass) from alumosilicate gel prepared by mixing solutions of sodium aluminate and sodium silicate diffusing from opposite sides. A study of the permeability of the composite membrane showed that virtually all the pores are sealed by the crystals grown within them. Dehydration above 200°C increases the permeability of the membrane by two orders of magnitude and subsequent rehydration does not restore the starting properties of the membrane.
