Keywords： microwave heating

The reduction kinetic condition of the direct solid-phase reduction of metal oxide powder containing coal by microwave heating is better than that by the conventional heating process. The research shows that the gas ionization during carbothermal reduction accelerates the carbon gasification reaction and interface chemical reaction, and it also improves the kinetic conditions of carbothermal reduction. Thus, the formation mechanism and process of gas ionization as well as its effect during the carbothermal reduction of metal oxides containing coal by microwave heating are studied.
