Abstract

Hydrogen isotope permeation through liquid Sn (Sn_L) supported by solid metals (M = Fe, Ni, V, F82H, and Pd) was examined at constant temperatures from 473 to 773 K and pressures from 0.67 to 93 kPa. The interaction between Sn_L and the supporting metal substrate formed an intermediate alloy (IA) layer at the interface due to corrosion caused by the chemical reactions of Sn_L with M. The Sn_L/M systems were categorized into two types according to the overall deuterium permeation behavior. In the Sn_L/Fe and Sn_L/Ni systems, the IA layer was crucial in governing the overall deuterium permeation flux. In the Sn_L/Pd system, deuterium permeation was strongly suppressed by the IA layers, whereas in the Sn_L/V and Sn_L/F82H systems, the rate-determining step for the overall deuterium permeation flux was the Sn_L layer. The Sn_L/V system exhibited the highest deuterium permeation flux, which was less affected by the formation of the IA layer. This result highlights the potential of V and its alloys as membrane windows for tritium extraction from Sn_L by permeation.

氢同位素通过不同金属基质支撑的液态锡的渗透模拟

在温度为473 ~ 773 K，压力为0.67 ~ 93 kPa的条件下，研究了固体金属（M = Fe、Ni、V、F82H和Pd）负载的液态Sn （SnL）中氢同位素的渗透。由于SnL与M的化学反应引起的腐蚀，SnL与支撑金属基体的相互作用在界面处形成中间合金（IA）层。根据总体的氘渗透行为将SnL/M体系分为两种类型。在SnL/Fe和SnL/Ni体系中，IA层是控制总体氘渗透通量的关键。在SnL/Pd体系中，IA层强烈抑制了氘的渗透，而在SnL/V和SnL/F82H体系中，SnL层是总氘渗透通量的速率决定步骤。SnL/V体系的氘渗透通量最高，受IA层形成的影响较小。这一结果突出了V及其合金作为渗透法从SnL中提取氚的膜窗的潜力。
