Abstract
Vacuum distillation of magnesium is considered one of the practical approaches for processing secondary biodegradable alloys of the Mg–Sn system. The process relies on the difference in the partial vapor pressures of magnesium and tin; however, its accurate description requires an understanding of the thermal behavior of the intermetallic Mg2Sn phase. In the present work, dimagnesium stannide was synthesized, containing 97.8% of the Mg2Sn phase and 2.8% Sn. The obtained specimen was used to further investigate the decomposition and possible dissociative evaporation of Mg2Sn to refine the process parameters of magnesium distillation.
