Abstrakt: Abstract: Volatilization of ultramicroamounts of spallogenic products (Mo, Tc, Ru, Re and Os) from the melts of irradiated Ag and Au metals under dynamic vacuum conditions at 10−3–10−2 torr O2 and H2O vapours and their separation in a thermochromatographic column are studied. The influence of the time of sublimation, the gas phase parameters and the materials of the crucible and the column are investigated. Possible reactions and chemical forms of volatile spallogenic products are discussed. Diffusion coefficients are defined for an Ag-melt case. The conditions of Re/Os and Mo/Tc/Ru separation are found. The possibility of using the Ag and Au melts in the ISOL-system is considered.
