Electrochemical Measurements of Oxygen Potentials in the Slag System CaO-P_2O_5-SiO_2-Fe_xO

摘要

The liquidus compositions of the four-phase assemblages in the quaternary system of CaO-P_2O_5-SiO_2-Fe_xO were determined at 1473 and 1573 K by employing electron probe microanalysis. Measurements were also made on the Fe_xO activities at temperatures between 1373K and 1699K by employing an electrochemical technique involving stabilized zirconia electrolyte.
