Abstract

The solution reaction for oxygen into molten silicon was studied in the temperature range from 1450 to 1550° C using immersion sensors with ZrO 2 -based solid electrolytes. The liquid silicon was held in a quartz glass crucible. The formation of SiO vapour was avoided by flushing with argon. The change of standard free energy for the reaction 1/2 O 2 (g, 1 bar) = [O] si was obtained as −518.220 + 0.1773 T kJ/mol. The solubility of oxygen in molten silicon in equilibrium with silica was compared with the results of other investigators
