摘要
The high-temperature Raman spectroscopy technique is applied to investigate the phase transition of LiBa O5 crystal. The result shows that the crystal is stable in the range of 293-893 K. When the temperature increases up to above 1107K, the phase transition occurs. In the liquid phase, Li2B4O7 crystal precipitates out. Up to 117314, the Li2B4O7 crystal disappears in the melt.
