摘　　要：在理论分析的基础上,以3N级金属钪为原料,对金属钪真空蒸馏提纯过程进行了研究,并通过真空蒸馏—电弧熔炼制备高纯金属钪锭。结果表明,在自行设计制作的蒸馏塔中,采用1 500℃预蒸馏、1 560℃蒸馏的工艺条件下,经过一次真空蒸馏、电弧熔炼即可获得纯度达99.995%的高纯金属钪锭。Vacuum distillation of scandium was investigated based on theoretical analysis with 3 N metal scandium ingots as raw materials.High purity scandium ingots were prepared by vacuum distillation and arc melting.The results show that 99.995% high purity scandium ingots can be obtained in self-designed and fabricated distillation apparatus under the conditions including pre-distillation temperature of 1 500 ℃and distillation temperature of 1 560 ℃.
