摘　　要：针对高纯铜靶材的制备难题,对4N阴极铜开展了十公斤和百公斤级的电子束熔炼提纯试验研究,采用辉光放电质谱仪、O-N-H分析仪和C-S分析仪对杂质成分进行了表征。结果表明,在真空度1.5×10^(-1)Pa,功率20 kW熔炼25 min得到的十公斤高纯铜的主控杂质含量在1×10^(-5)(质量分数)以下,氧含量在2×10^(-6)以下;在同样的熔炼条件,以1.8 mm/min的速度定向凝固制备的百公斤级高纯铜锭主控杂质元素含量在2.373×10^(-6)以下,氧含量在2.2×10^(-6)以下。Test Research of purification of 4N cathode copper in both the 10 kg and 100 kg classes was conducted to address the challenges in preparing high-purity copper target materials.The characterization of impurities was conducted using a glow-discharge mass spectrometer,an O-N-H analyzer and a C-S analyzer.Results show that the master impurity content of 10 kg high purity copper is under 1×10^(-5)(mass fraction),the oxygen content is under 2×10^(-6 )when the vacuum degree is 1.5×10^(-1) Pa,the power is 20 kW smelting for 25 min;at the same smelting conditions,the master impurity content is under 2.373×10-6,the oxygen content is under 2.2×10^(-6) of high purity copper ingot in 100 kg class prepared by directional solidification with 1.8 mm/min velocity.
