N2 - We prepared a niobiophosphate-glass-crystallizing tungstenbronze-type Ba2NaNb5O15 and measured elastic light scattering spectra in situ in the glass-ceramics fabrication regime. We found that the studied glass possesses a strong tendency for phase separation into Al2O3-P2O5 and Nb-rich regions prior to crystallization. It is suggested that the tungstenbronze phase crystallizes in the Nb-rich region separated from the supercooled liquid phase. This study demonstrated that in situ Raman spectroscopy is also useful for observing the phase-separation dynamics in glass.
