Abstract

The solubility of oxygen in (TeO2)0.78(WO3)0.22 glass melt at 640оС by the use of technique based on the measurement of oxygen pressure over the melt in evacuated closed system has been studied. The solubility of oxygen at pressure of 3.9×103 Pa over the melt is equal to (5.6 ± 0.6)×10-6 mole/cm3 . A linear increase of solubility is observed in the pressure range from 1000 to 5000 Pa and the effective Henry coefficient is 5×108 Pa/mole/cm3..
