Beschreibung
Zusammenfassung:	FIELD: chemistry; physics.SUBSTANCE: invention relates to physical chemistry, gas analysis, vacuum engineering and can be used for separation of atoms and hydrogen ions, as well as its isotopes from gas mixtures. Method of making a membrane for extracting atoms and ions of hydrogen from gas mixtures based on metals of 5th group of periodic table of elements, niobium, vanadium, tantalum and their alloys with each other, comprising removal of surface carbide by thermal treatment of membrane in oxygen at temperature of membrane from 1,400 °C to 1,550 °C and oxygen pressure from 10Pa to 10Pa.EFFECT: high stability of operation of membrane.1 cl, 2 dwg Изобретение относится к физической химии, газовому анализу, вакуумной технике и может быть использовано для выделения атомов и ионов водорода, а также его изотопов из газовых смесей. Способ изготовления мембраны для выделения атомов и ионов водорода из газовых смесей на основе металлов 5-й группы Периодической системы Менделеева, ниобия, ванадия, тантала и их сплавов друг с другом, в котором производят удаление приповерхностного карбида путем термической обработки мембраны в кислороде при температуре мембраны от 1400°С до 1550°С и давлении кислорода от 10Па до 10Па. Технический результат - повышение стабильности работы мембраны. 2 ил.
