摘要
用等温饱和法测定了单一稀土氧氯化镧 (LaOCl)和混合稀土氧氯化物 (REOCl)在冰晶石 (Na3AlF6 ) 氧化铝 (Al2 O3)熔体中的溶解度。结果表明 :LaOCl和REOCl的溶解度变化规律一致 ,即其溶解度随温度升高而增大 ;随着冰晶石分子比增加而增大 ;当有 4 0 % (质量分数 )Al2 O3存在时 ,其溶解度相应减少。
The solubility of single rare earth element oxychloride (LaOCl) and mixing rare earth elements oxychloride(REOCl) in the melt of cryolite(Na 3AlF 6) alumina(Al 2O 3) was determined with isothermal saturation method. The effects of temperature and molecular ratio of cryolite and Al 2O 3 on the solubility were discussed. The results show that the solubility change of LaOCl and REOCl is coincident, that is, the solubility of LaOCl increases with the increasing of temperature and the molecular ratio of cryolite. When there exists 4 0% (mass fraction) Al 2O 3, the solubility decreases.
