| 摘 要： | 首次尝试利用开路电位-浓度曲线法测定合金的浓度, 并用阳极计时电位法快速测定Li在液态Al中的扩散系数。720℃下Li在液态Al中的扩散系数DLi/Al=4.94×10ˉ^5cm^2·gˉ^1,与根据Stokes-Einstein方程计算得到的理论值DLi/Al=4.85×10ˉ^5cm^2·sˉ^1相吻合。

| Abstract: | The rest potential-concn. curve was first applied to measure the concentration of an alloy. Attempt to use the V-c curve of Al-Li alloy in measuring the diffusion coefficient of Li atom in liquid Al with anode chronopotentiometry at 720? was made and DLi/Al = 4.94 ?10-5 cm2.s-1 was obtained. The value is well consistent with the theor. value, DLi/Al = 4.85 ?10-5 cm2.s-1 in terms of Stokes-Einstein equation. |
