摘要
本文研究了在NaCl-KCl-YCl_3熔体中,电化学合金化Y-Cu体系的热力学行为。用恒电位电解断电后的电极电位-时间曲线测定了形成YCu_6,YCu_4,YCu_2,YCu等金属间化合物反应的ΔG(973-1103K),结果表明测量方法简单可靠。
The electrochemical alloying of Y-Cu system in molten NaCl-KCl-YCl_3 has been investigated. The free energy changes of the formation reactions ofthe intermetallic compounds, including YCu_6, YCu_4, YCu_2, YCu(973--1103K), weredetermined by means of electrode potential-time curves of the working electrodeafter potentiostatic electrolysis. The results indicate that the potential-time methodis simple and reliable.
