摘要：

The number of bubbles was monitored in antimony oxide fined R2O-MxOy-SiO2 and R2O-CaO-Al2O3-SiO2 glasses (R=Na, K, M=Ca, Mg, Ba, Sr, Zn, B, Al, Ti, x=1 or 2, y=1, 2 or 3) in order to evaluate the fining efficiency. Electrochemical measurements of oxygen activity were used to, in situ, monitor the fining characteristics and conditions in some of the investigated glass melts. The results showed that an increase of the calculated optical basicity was related to ail increased number of bubbles in the glass samples. The oxygen activity in the melt during fining decreased With increased optical basicity.
