Laser-induced reduction of iron ore: Trends of the chemical distribution across the domains

“…Aluminium as a reducing agent candidate was studied for different purposes, including railway welding [17], pyrotechnics or metal matrix composite synthesis [18,19]. The well explored thermite reaction between Al and iron ore [20][21][22][23] is initiated in a temperature window of 1300-1360 °C. X-ray high speed, high resolution imaging of a thermite combustion process enabled to measure the spatial and temporal evolution of liquid domains during the process kinetics [17].…”
