摘　　要：在氯化装置中用气相法制备无水氯化钇,研究了氯化氢气体用量、反应温度、反应时间、料层厚度等对无水氯化钇中RECl3含量的影响。结果表明,当氯化氢气体用量为理论量1.6倍、反应温度450℃、反应时间36h、料层厚度10cm时,得到的高纯无水氯化钇中RECl3平均含量99.15%,氧化稀土的平均氯化率为97.89%,稀土平均收率为99.33%。Anhydrous yttrium chloride was prepared in chlorination equipment by gas phase method. Effects of hydrogen chloride gas consumption, reaction temperature, reaction time, and thickness of feed layer on RECI：- content in anhydrous yttrium chloride were investigated. The results show that average RECl3 content in high purity anhydrous yttrium chloride is 99.15% with average chlorination rate of rare earth oxide of 97.89% and average yield of rare earth of 99.33% under the conditions including hydrogen chloride gas consumption of 1.6 times of theoretical dosage, reaction temperature of 450 ℃, reaction time of 36 h, and thickness of feed layer of 10 cm.
