Geometric standard deviation of particles as a function of liquid paricle percentage and holding time in Fe-O-Al-Ca melts. (a) ln σ values of particle as a function of liquid particle percentage in Fe-O-Al-Ca melts after deoxidation at 1600 °C for 3900 s; (b) ln σ values of particle as a function of holding time in experiment A1C1 ([% Al]i = 0.05 and [% Ca]i = 0.25), A1C3 ([% Al]i = 0.05 and [% Ca]i = 0.78) and A2C3 ([% Al]i = 0.25 and [% Ca]i = 0.78).
