This study of purification parameters in vacuum distillation of magnesium was performed using primarily AM100 magnesium alloy as the raw material. The ratio of purification increases with increasing purification time in the AM100 magnesium alloy and is higher than the ratio of purification of the pure magnesium. The ratio increases with increasing purification temperature in the AM100 and AM60 magnesium alloys. The compositions at the AM100 alloy are almost the same after purification at temperatures 555°C, 600°C and 625°C. By a hole type condenser, quantities of impurities of the distilled pure magnesium inside and outside the condenser are about the same. The Zn concentrations of the purified AM100 and AM60 alloys are, however, more inside than outside the condenser. Pure magnesium of less than 30ppm Zn can be converted to pure magnesium of 10ppm Zn by the vacuum sublimation method.
