| Abstract |
Low melting glasses in the MoO3-Nd2O3-Bi2O3 system were obtained at slow (102 K/s)
and high cooling rates (104-105 K/s). The amorphous state of the samples was proved by X-ray
diffraction. Comparative analysis of the infrared spectra of the obtained glasses and other available
molybdate spectral data was carried out. The structure of glasses with a high MoO3 content was
found to consist of corner shared MoO6 units. The increasing of Nd2O3 and Bi2O3 lead to partial
transformation of MoO6 to MoO4 units, due to breaking of Mo-O-Mo linkage. |
