In-situ spectroscopy and two-color thermography during microwave irradiation in materials processing

研究成果: Conference contribution

抄録

In ?-Fe2O3 + C system, a plasma discharge (such as CN and N2) during microwave E-field irradiation and local temperature distribution is are investigated by using in situ emission spectroscopy device and high-resolution two-color thermography. The time development of excited plasma in E-field irradiation demonstrate that excited N2, C and CN were observed at first but CN excitation was sustained at least 3 seconds. In microwave H-field irradiation, -Fe2O3 powders were selectively heated compared to carbon. Excited CN results in enhancement of the reduction reaction in addition to thermal reduction in E-field irradiation, and selective heating of -Fe2O3 suggests a reduction reaction proceeds in thermally non-equilibrium condition in H-field irradiation.
