英文摘要	研究了温度、浓度对ＺｎＣｌ２－尿素熔体电导的影响，ＺｎＣｌ２－ＮａＣｌ－尿素熔体的电导率（１２５℃）可达３０ｍｓ·ｃｍ－１以上．用循环伏安曲线、恒电位电解及断电后的电位－时间曲线，研究尿素熔体中Ｚｎ２＋的电还原和锌在钛、铜电极上的电沉积．Ｚｎ２＋的电还原为一步可逆过程，锌沉积在铜电极上会形成ＣｕＺｎ５合金．Ｚｎ２＋在熔体中扩散系数为１．３×１０－６ｃｍ２·ｓ－１（１２５℃）; The electric conductivities of ZnCl 2 Urea melts were determined.The influences of temperature and concentration on the conductance have been studied.The cylic voltammetry,potentiostatic electrolysis and open circuit potential time curve after electrolysis,X ray diffraction were used to investigate the electroreduction of Zn 2+ , electrodeposition of zinc on some electrodes in urea metal chlorides melt. The conductivity of urea NaCl ZnCl 2 melt can reach to over 30 ms·cm -1 (125 ℃), and has a liner relationship with temperature from 108 to 140 ℃. The electroreduction of Zn 2+ to zinc is reversible at one step, and CuZn 5 alloy has been found on copper electrode. The diffusion coefficient of Zn 2+ in urea NaCl ZnCl 2 melt was determined as 1.3×10 -6 cm 2·s -1 (125 ℃).; 作者联系地址：中山大学化学系; Author's Address: Department of Chemistry, Zhongshan University
