Two hypotheses exist to explain the viscosity decrease mechanism of calcium ferrite (CF) melts during isothermal melting in air: variations in either the short-range structure near Fe3+ or the Fe redox state. Here, the synchrotron X-ray total scattering pattern of an aerodynamically levitated CF droplet was monitored during isothermal melting. No variations were observed in the short-range structure of the melt for 1800 seconds, indirectly suggesting that redox state variations dominate the viscosity.
