On basis of silica nanopowder «tarkosil» (produced by the authors through new technology of raw material evaporation by electron beam), the nanoporous ceramics with open porosity were used, and its separation properties were studied. For the ceramics, obtained at different sintering temperatures, their specific surface, porosity, and separation factor were determined. The obtained ceramics were applied for separation of four combinations of gases: He/Ar, He/N2, He/CH4, and N2/Ar. The possibility (using the created by the authors ceramics) of helium enrichment his mixtures with more heavy gases was shown.
