N2 - An Fe-O drop of ~0.4 g in an alumina crucible was quenched from ~2200 K (~1927 °C) at a cooling rate of −87 K/s by flowing He gas at a flow rate of 25 L/min STP. A deep undercooling of approximately 200 K was obtained regardless the oxygen content in the sample. According to the classical nucleation theory, the contact angle between a solid Fe nuclei and the Al2O3 substrate was estimated to be 53 (±4) deg.
