Abstract

The invention discloses a high-cycling-capacity ZrCo-based hydrogen isotope storage alloy, preparation of the alloy and application of the alloy to storage, supply and recovery of hydrogen isotopes. The chemical general formula of the high-cycling-capacity ZrCo-based hydrogen isotope storage alloy is Zr(1-x)NbxCo(1-y)Niy, wherein x is larger than 0 but smaller than or equal to 0.5, and y is largerthan 0 but smaller than or equal to 0.5. A preparation method of the alloy includes the following steps that (1) Zr, Nb, Co and Ni elementary substance raw materials are mixed according to the proportion in the chemical general formula and then are placed into a magnetic suspension induction smelting furnace; and (2) smelting, cooling and solidifying are performed under the protection of an argonatmosphere to prepare the high-cycling-capacity ZrCo-based hydrogen isotope storage alloy. The method is simple in step and high in safety, the prepared hydrogen isotope storage alloy is not requiredto be subjected to vacuum operation in the circulation process, the method is still applicable in complex hydrogen isotope scenes, and the method has long-term significance in promoting application and popularization of the ZrCo-based alloy in the field of hydrogen isotope storage.

Description

technical field [0001] The invention relates to the technical field of hydrogen isotope storage and supply, in particular to a ZrCo-based hydrogen isotope storage alloy with high circulation capacity and its preparation and application. Background technique [0002] The exploitation and use of traditional fossil energy have caused energy crisis and environmental pollution, two difficult problems to solve. Therefore, the development of clean energy that is pollution-free, renewable and highly utilizable has become the main theme in the field of energy research. [0003] Deuterium-tritium nuclear fusion reaction can release huge energy, and it has the characteristics of clean, safe and efficient. In view of this, countries around the world have jointly built the International Thermonuclear Experimental Reactor (ITER) to further explore controllable nuclear fusion technology. During the operation of the reactor, the outside world needs to supply or recover hydrogen isotope gas...
