Venue：Tsukuba

Infrared absorption of xNa2O-(100-x)B2O3 (x=0,10, 15, 20, 30), 20Na2O-20B2O3-60SiO2 and 30Na2O-10B2O3-60SiO2 glass melts were measured in the temperature range from 100 to 700°C. Absorption at 2700 cm-1 which originates from BO stretching vibration of three-fold coordinated boron increased with increasing the temperature above Tg. This should be due the formation of BØ3 unit by decomposition of BØ4 to BØ3 + NBO and of boroxol ring to loose BØ3.

Venue：Nagoya

In the glass manufacturing process, bubbles should be removed from glass melt. Many efforts have been made to produce glass products without any bubbles. It is considered that electrolytic decomposition of glass melt should be one origin of bubble generation. However, the mechanism is still unclear. In order to develop manufacturing process with high efficiency, it is of primary importance to evaluate the electrolytic decomposition of glass melt. In this study, electrochemical reactions of silicate glass melt under alternating voltage application are investigated, and a mechanism of bubble generation is discussed using the Nernst equation for oxygen evolution.

Analysis of the high temperature thermal conductivity of glass by considering radiative heat transfer

Language：Japanese Presentation type：Poster presentation

Venue：Nagoya

Thermal diffusivity(D) was measured for vitreous SiO2, soda lime silicate(SLS) glass and E glass from room temperature to 1073 K. Temperature response curves were obtained by Step heating method. Values of D were estimated by using an analysis method which removes radiative heat transfer effect from irradiated to back faces of the transparent sample. Reliable values of D were obtained for vitreous SiO2. D of SLS glass and E glass decreased more than 10% around the glass transition temperature.

Synthesis and the structure of hard borosilicate glass

Venue：Nagoya

The structure on MgO-B2O3-SiO2 (4:2:4 and 6:2:2 in molar ratio) glasses has been investigated by means of Mg, B K-edge XANES and Raman spectroscopy. Highly de-polymerized borate groups, which almost consist of B[3], was observed in the glass with the higher MgO content, suggesting that the glass has more closed structure. As the evidence, the glass exhibits fairly high Young's modulus, 138 GPa. However, the glass with lower MgO content was more tougher (high crack resistance) because of the enhancement of the network structures, which consist of B[4].
