Density and surface tension of liquid iron oxides
F. Millot, J.C. Rifflet, G. Wille and V. Sarou-Kanian
New data are presented for the density ρ and the surface tension σ of the liquid oxides FeOX in the range of x between 1.05 and 1.35 and temperatures T from 1865 to 2155 K. The results obtained with contactless techniques indicate that ρ. and σ are almost constant with T and x within uncertainties. Practical values are ρ = 4.35 ± 0.1g/cm3 and σ = 0.59 ± 0.02 N/m.
