Study on Carbothermal Reduction Reaction of FeNb2O6 in Microwave Field AITranslate
Abstract AITranslate
The reduction reaction of FeNb2O6 in microwave field was investigated by combining microwave heating with the carbon thermal reduction characteristics of FeNb2O6.The effects of temperature, particle size and carbon content on the reaction rate of microwave carbothermal reduction of FeNb2O6 were studied by microwave thermogravimetry, and the kinetics of the carbothermal reduction of FeNb2O6 in microwave field was also analyzed.The results show that FeNb2O6 has a good heating characteristics during microwave heating.Compared with conventional heating, FeNb2O6 can react at a lower temperature in microwave field under the same holding time and temperature.The weight loss rate of FeNb2O6 in microwave field increases with the increase of temperature, while the weight loss rate of microwave carbothermal reduction can be increased by increasing the particle size and carbon content at the same temperature.According to the kinetic analysis, the apparent activation energy of carbothermal reduction of FeNb2O6 in microwave field is 127.3 kJ/mol, which is lower than that of conventional heating, indicating that microwave heating can reduce the activation energy of the reaction.
