Abstract The structure of the emission spectrum in the
near-UV range (240 nm – 310 nm) changes drastically from the
continuous spectrum to a discrete line spectrum with increasing sample
temperature during the carbothermic reduction of magnetite in a 2.45 GHz
microwave multi-mode furnace. The continuous spectrum can be assigned as a
cathodoluminescence of magnetite. The dynamic evolution of the spectrum from
continuous to discrete represents the progress of the reduction from
magnetite to iron. Key Words: Microwave iron making, reduction process, highly thermal nonequilibrium, spectroscopy, near-UV emission, continuous spectrum, solid-state fluorescence, cathodoluminescence. |
