| 摘 要： | 以微波辅助碳热还原法对五氧化二钒进行还原氮化。测定了炭黑、活性碳和石墨作为还原剂的混合物料在微波场的升温曲线,并采用热重分析法考察了微波场中不同输入电流对物料还原程度的影响。结果表明,3种还原剂中炭黑的吸波性能和还原性能最佳,在输入电流为16 A、微波辐照时间105 min时,炭黑物料的还原度为0.96,当辐照时间延长至120 min时,氮化反应迅速,此时样品氮含量为16.36%。

| Abstract: | Reduction of V2O5 in microwave field was achieved with Carbon Heat Reduction process. The characteristics of temperature increase of different reducing agents, such as carbon black, active carbon and graphite carbon, were investigated in microwave field. Thermogravimetric analysis was employed to study the effect of microwave input current on the degree of reduction of samples. The results indicated that carbon black was of good absorbing microwave characteristic and reducing property. When the input current was 16 A and irradiation time was 105 min, the degree of reduction was 0.96. While irradiation was extended to 120 min, nitridation reaction was almost complete, at this case the nitride content of the sample was 16.36%. |
