N2 - In situ observation of Raman scattering in glassy sanbornite (BaSi 2 O5) showing homogeneous nucleation was performed during heating to investigate the structural variation in the glassy/supercooled-liquid phase in the pre- and postnucleation regimes. It was observed that the formation of Q2 units accelerates around 400 °C, which is well below Tg, just after structural relaxation in the Ba-enriched/-cohesive region. The relation between the structural variation and the nucleation trend in glassy sanbornite was also discussed on the basis of transmission electron microscopy and in situ Raman results and previous Boson observation [Takahashi Appl. Phys. Lett. 94, 211907 (2009)].
