测定了尿素—ＬｉＣｌ、尿素—ＮａＣｌ、尿素—ｋＣｌ、尿素—ＣｕＣｌ＿２、尿素—ＮｉＣｌ＿２、尿素—ＮａＣｌ—ＣｕＣｌ＿２、尿素—ＮａＣｌ—ＮｉＣｌ＿２熔体的电导率，研究了温度、浓度、碱金属离子大小对电导的影响。在所研究的温度范围内（１００～１３６℃），上述体系的电导率与温度成直线关系，尿素一碱金属氯化物熔体的电导率随阳离子半径增大而减少，且与阳离子半径平方的倒数成线性关系。尿素—ＣｕＣｌ＿２（０．１～１．０ｍｏｌ·ｄｍ￣（－３））的电导率在０．８ｍｏｌ·ｄｍ￣（－３）附近出现最高点，在０．７４ｍｏｌ·ｄｍ￣（－３）氯化物浓度附近，摩尔电导的顺序是ＬｉＣｌ＞ＮａＣｌ＞ＫＣｌ＞。
The conductivity of urea-NiCl, urea-kCl, urea-CuCl_2, urea-NiCl_2, urea-NaCl-CuCl_2 and urea-NaCl-NiCl_2 melt were measured and the effects of temperature, The effect of conductance. In the studied temperature range (100 ~ 136 ℃), the conductivity of the above system has a linear relationship with the temperature. The conductivity of the urea-alkali metal chloride melt decreases with the increase of the cation radius, and is proportional to the square of the cation radius Countdown into a linear relationship. The conductivity of urea-CuCl_2 (0.1-1.0 mol · dm -3) appeared the highest point around 0.8 mol · dm -3, and at 0.74 mol · dm -3 of chlorine Near the chemical concentration, the order of molar conductance is LiCl> NaCl> KCl>.
