Abstract
By employing an electrochemical technique involving stabilized zirconi a as solid electrolyte and Mo + MoO2 mixture as reference electrode, t he equilibrium oxygen partial pressures for three-phase assemblages of CaSiO3(s) + Ca3Si2O7(s) + {CaO + SiO2 + FexO} melt and Ca3Si2O7(s) Ca2SiO4(s) + {CaO + SiO2 + FexO} melt were determined as: log {P-O2 (C S + C3S2 + L)/bar} = -3.22 13000/(T/K) +/- 0.05 log {P-O2 (C3S2 + C2S + L)/bar} = -0.92 16400/(T/K) +/- 0.04, respectively, where CS, C3S2 a nd C2S indicate CaSiO3(s), Ca3Si2O7(s), and Ca2SiO4(s), respectively.
