High Temperature Raman Spectrum of Phonon Vibration Like Modes for Aggregation Structure in Silicate Melts

Measurement of low, medium & high wavenumber Raman spectrum for MCAS,MNAS, GCAS and GNAS et al nine series samples have been finished by Jobin Yvon T64000 LWRS (50-200cm(-1)) and Jobin-Yvon LabRAM HR800 RS(400-600cm(-1) & 900-1200 cm(-1)). The measurement values is listed in Tab.l. The relationship curves between the frequency of phonon vibration like mode (v (TA) & v (TO+LO)) and aggregation size (Ls) (v'~Ls curves) are shown in Fig.1.
