【摘要】：采用氯化铵和氧化铈为原料,利用自制成套氯化装置干法制备无水氯化铈,实现了无水氯化铈的批量生产。扩大试验结果表明:在氧化铈50 kg,氯化铵用量为理论量的2.4倍,均匀混料,反应温度450℃,反应时间32 h,料层厚度15 cm的条件下产品无水氯化铈纯度可高达99.35%。
[Abstract]:Using ammonium chloride and cerium oxide as raw materials, anhydrous cerium chloride was prepared by dry process in a self-made chlorination plant, and the batch production of anhydrous cerium chloride was realized. The expanded test results showed that the amount of ammonium chloride was 2.4 times of the theoretical amount when cerium oxide was 50 kg. Under the conditions of homogeneous mixing, reaction temperature 450 鈩，
