研究了玻璃渣法从镧镍合金中提取稀土的工艺。X射线衍射和电子探针分析表明，用B_2O_3玻璃渣法制备的La-Ni合金由Ni和Ni_3B相组成。在合金中没有发现LaNi_5相和La氧化物相等含La相。化学分析证实，玻璃渣法生产的合金中La含量非常有限。然而，玻璃渣材料含有大量的镧。采用玻璃渣法用B_2O_3成功地提取了La-Ni合金中的La。
The use of the glass slag method in the extraction of rare earth from La–Ni alloys was studied. X-ray diffraction and electron probe microanalysis studies revealed that the La–Ni alloys produced by the glass slag method using boron trioxide consisted of Ni and Ni_3B phases. No La-containing phase such as the LaNi_5 phase and the La oxide phase was found in the resultant alloys. The chemical analyses confirmed that the La content in the alloys produced by the glass slag method was very limited. However, the glass slag materials contained a large amount of lanthanum. The La in the La–Ni alloys was successfully extracted by the glass slag method using boron trioxide.
