本文计算了NdF3-LiF-Nd2O3体系各物质的理论分解电压。结果表明，采用惰性阳极，理论分解电压按Nd2O3、NdF3、LiF顺序依次增大，温度升高，理论分解电压降低；采用活性阳极(石墨)时，Nd2O3与石墨反应生成CO和CO2，其理论分解电压较小，反应较易发生，尤以生成CO的反应更易发生。但当电流密度较高或Nd2O3浓度较低时，可能生成碳氧氟化合物及氟碳化合物，并发生阳极效应，各物质的理论分解电压也随温度的升高而降低。
The theoretical decomposition voltage(also called EMF)for substances in NdF3-LiF-Nd2O3 system was figured out in present paper.The results indicate that the EMF in inactive anodes increases in sequence of Nd2O3,NdF3 and LiF,and that it drops with rising of temperature.While using active materials as anode,such as graphite,Nd2O3 reacts with graphite,with CO or CO2 as the product,the EMF is much lower.And the two reactions can occur much easier than the other reactions,especially that one whose product is CO. But at a higher current density or under a lower Nd2O3 concentration,COFn and CxFy may be obtained.As a result ,the anode effect can occur.The EMF on active anode decreases with temperature,too.
