What is it about?
This study focused on the melting properties of aluminosilicate glasses with different boron contents, including the evolution of bubbles in the melt, and the influence of silica sand particle size on bubbles and uniformity of glass samples, as well as the surface tension and resistivity of glass melt.

Why is it important?
Chemical reaction of the batches for TFT-LCD and OLED substrates were similar, while the carbonate decomposition was completed at higher temperature for OLED substrate at about 1060 ℃ compared to 1020 ℃ for TFT-LCD substrate. (2) SnO2 showed better fining effect than SnO, both for TFT-LCD and for OLED substrates. Compared to alkaline glass, three hours’ fining process was not sufficient for TFT-LCD and OLED substrates. And it took more time for OLED substrate. (3) Silica sand with particle size in the range of 150 ~200 mesh exhibited the best melting quality in bulk glass samples judged by the number of visible bubbles and SiO2 between different positions of samples. (4) The molten resistance at 1600 ℃ was 44 •cm and 97 •cm for TFT-LCD and OLED substrates, respectively. And faster increase of resistance with temperature decrease was observed for OLED substrate.
