中文摘要：

研究了在氩气气氛下用氯化铵作为氯化剂氯化氧化铈制备高纯无水稀土氯化铈的工艺条件,通过正交实验考察了物料配比、反应温度、反应时间的影响,并用XRD对无水稀土氯化铈进行了表征.结果表明,氯化铈的最佳制备工艺条件为：物料摩尔比n（NH4Cl）：n（CeCl4）=12：1,氯化焙烧温度300℃左右,氯化时间30min.此条件下氯化率为96.16%,产物含杂量小于5%.

英文摘要：

Technological conditions in preparation of high purity anhydrous cerium chloride with ammonium chloride as chlorinating agent to chlorinate cerium oxide in argon atmosphere were studied.The reaction temperature and time,and dosing ratio of reactants by orthogonal experiments for optimization of the preparation conditions were examined,and its product was characterized by XRD.The results showed that by chlorinating cerium oxide for 30 min with ammonium chloride dosage in a molar ratio of n（NH4Cl）：n（CeCl4）= 12：1 at 300℃,the chlorinating rate of oxide reached 99.6%,the impurity in the anhydrous cerium chloride product was less than 5%.
