Purification of Aluminum up to 7N level by Ultrahigh Vacuum Melting
Publikováno v: 広島国際学院大学研究報告. 50:1-7
This paper examines the purification of aluminum through the use of ultrahigh vacuum melting. To improve its purity up to 7N（ 99.99999％ pure） level, aluminum was melted in a vacuum of 2-4×10-6 Pa for 30 min and solidified gradually. The melted
