摘要

采用热解吸法研究了氚在锂陶瓷γ -LiAlO2 中的扩散行为。根据不同线性升温速率下的氚释放曲线

分别测出了以HTO形式释放的氚和以HT形式释放的氚的表观扩散活化能分别为（2 53± 50 ）kJ·mol-1和（12 7± 5）kJ·mol-1

Abstract

Tritium release behavior from the pellets of γ-LiAlO 2 was studied by the thermodesorption method. According to the measured curves of different heating rates

the nominal diffusion activation energies of HT and HTO were calculated. Their values were (127±5)kJ·mol -1 and (253±50)kJ·mol -1 respectively.
