Abstract

Two topics of IR-diagnostics performed in the fundamental experiment of microwave iron making will be presented. One is tunable diode laser absorption spectroscopy for both CO and CO₂ gas generated during microwave irradiation. The other is spectroscopic thermography for iron oxide powder of which surface would be metalized by microwave carbothermic reduction.
