摘要
FIELD: chemical industry; nuclear technology; methods of production of a high-enriched isotope - silicon-28.;SUBSTANCE: the invention is pertaining to the field of chemical industry and nuclear technology, in particular, to the methods of production of a high-enriched isotope - silicon-28. The initial trichlorosilane passes through a separating cascade of gaseous whizzers. In the routes of the last cut of the cascade stages mount devices for realization of reaction of the isotopic exchange, which contain a solid accelerator with a developed surface, for example, with a fibrillar sorption-active substance filled with an activated charcoal. The devices may be heated up to increase effectiveness of operation. Usage of these devices allows to bring trichlorosilane in the stages of the cascade to equilibrium. The target isotope - silicon-28 is separated from the routes of the light fraction. The invention allows to produce a high-enriched (more than 99.9 %) isotope - silicon-28 with high efficiency and a degree of extraction.;EFFECT: the invention ensures production of a high-enriched isotope - silicon-28 with a high efficiency and a degree of extraction.;2 cl, 2 tbl
