This study investigates the effects of vacuum and hydrogen atmospheres on the removal of metallic and non-metallic impurities during zone melting of Al, Cu, and Ni. The results show that while hydrogen had minimal impact on metallic impurity removal, it significantly enhanced the elimination of non-metallic impurities, particularly oxygen, in Cu and Ni. The introduction of hydrogen reduced oxygen levels by over 95 % in Ni and 44 % in Cu, and also improved the removal of carbon and sulfur. However, in Al, hydrogen refining proved less effective due to the stability of Al₂O₃ and the tendency of Al to form hydrides. © 2024 Elsevier Ltd
