Abstract
In the present work, the behavior of un-coagulable CO was experimentally investigated during the condensation process of carbothermic reduction of magnesia at condensing zone temperatures ranging from 923 K to 1223 K. Magnesium powders and magnesium lump condensates were produced under different conditions and characterized by scanning electron microscopy and energy-dispersive X-ray spectroscopy. The reverse reaction products C and MgO were formed following the process of magnesium vapor condensation and we just found the nearer the temperature of the condensation zone approached the liquid transition temperature, the lower the rate of the reverse reaction between CO and magnesium vapor. So, decreases in the rate of the reverse reaction of magnesium were possible by controlling the condensation temperature in experiments.
