The High temperature Raman spectra of BGO crystal and melt were studied. The structures of BGO crystal and melt were analyzed. The rule of structure change of BGO crystal with increasing temperature was analyzed. The results show that the peaks of spectra move to the low wavelength and broaden in different degrees. The intensities of spectra peaks decrease, too. And there exit GeO4 and BiO6 bond structure in the melt of BGO crystal, while the bond between GeO4 and BiO6 bond structures disappear, so those two structures are unattached in the melt.
