The volatilization and condensation behaviours of magnesium during the sublimation and desublimation processes were investigated at 10 Pa, respectively, The average volatilization rate increases with increasing temperature, but decreases with increasing specific surface area. The condensation position at which the magnesium vapor becomes solid is further away from the heating source with the temperature of the heating source increasing, but the value of the condensation temperature is maintained in an interval (603-733 K). It can be beneficial to the condensation and crystallization of magnesium vapor with increasing the temperature and temperature gradient of the condensing zone appropriately.
