Effects Of Batch Compositions On The Redox States Of Antimony In Tv-Glass Melts

To elucidete the effects of batch compositions on the redox states of antimony in TV-glass melts, the partial pressure of oxygen (p02) in the glass melts was measured by oxygen sensor. It was observed that p02 in the glass melt increased with increasing temperature due to the release of oxygen from the reduction of Sb5+ to Sb3+. Addition of sodium nitrate in the batch or increasing batch/cullet ratio helped to keep the glass melts more oxidizing due to increasing the concentration of pentavalent antimony (Sb5+), which resulted in the increase of p02 in the glass melts. Increase of the size and decrease of the total number of residual bubbles in glasses were observed with increasing p02 in the glass melts due to increasing temperature.
