| 摘 要： | 钯材的高速载氘对金属-氢同位素系统和氢能应用领域的研究具有重要的意义.本文研究了以海绵钯粉为原料通过脉冲烧结制备多孔钯块材的新工艺,用SEM和XRD分析了制备的多孔钯块材的微观结构形貌和相组成,并进一步研究了多孔钯块材的气体载氘行为.结果表明,采用脉冲烧结工艺可制备出孔隙率为81.6%的纯净多孔钯块材,氘在该钯材中的初始载入速度较高但迅速降低,80 s内即可完成约90%氘的载入;载氘开始约10 s后,氘的载入速度下降到较低的水平并缓慢衰减. |

| Abstract: | High-speed deuterium loading in palladium is of great importance in the research of Metal-Hydrogen isotope system and applications of hydrogen energy. In this paper, porous Pd bulk prepared by a new pulse sintering technology is studied. The microstructure and phase of the porous Pd bulk are characterized by SEM and XRD. In addition, the deuterium gas loading behavior of the porous Pd bulk is investigated. The results show that clean porous Pd bulk with porosity of 81.6% can be prepared. The initial loading... |
