摘要
研究了不同温度下3种稀土硝酸盐:Ce(NO3)3、La(NO3)3、Y(NO3)3在非水溶剂中(无水乙醇、丙酮、DMF)的电导性质,并利用公式求得25℃时Ce(NO3)3、La(NO3)3、Y(NO3)3的摩尔电导率。并讨论了它们的电导率随温度和浓度的变化关系以及溶剂对电导率的影响。相同温度下,稀土硝酸盐的电导率随浓度的增大而增大;相同浓度下,稀土硝酸盐的电导率随温度的升高而增大。
The conductivity of three rare- earth nitrates：Ce（NO3）3 ,La（NO3 ）3 and Y（NO3 ）3 ,was measured in non - aqueous solvent such as：C2H3OH,CH3COCH3 、DMF at different temperatures. The use of formula has calculated the molar conductivity of Ce（NO3 ）3, La（NO3 ）3 and Y（NO3 ）3 at 25 ℃ .The effect of temperature and concentration and solvent on electrical conductivity of rare- earth nitrates was discussed. At the same temperature, the dectrical conductivity increases with increase of concentration. At the same concentration, the electrical conductivity increases with increase of temperature.
