This paper first studied the structure of nioboborate glass melts by high temperature Raman spectra and high temperature IR spectra. The experimental results indicated that the B
Ⅲ
-O-B
Ⅳ
bond is very unstable in the boric glass. Under the heating field the bond B
Ⅲ
-O-B
Ⅳ
is converted to a stable big-mixing π bond or broken down. When Nb
2
O
5
is added the [NbO
6
] and [NbO
4
]will replace [BO
3
] and compose the structure network of glass. In this work the structure model of nioboborate glass melts was established.
