| Abstract: | Li 2B 4O 7 crystal, glass and its melt from room temperature up to 1773 K are studied by high temperature Raman spectroscopy using pulsed semiconductor laser and time-resolved detection technique Temperature-dependent characteristic spectra and phase transition are observed It shows that there exists several kinds of the micro-structure units in the melt and their relative densities vary significantly with the increasing temperature Structure differences between Li 2B 4O 7 crystal, glass and its melt were also discussed |
