摘要：

The glass formation regions for the SeO2-MoO3-MnOm systems (MnOm = Bi2O3, Sb2O3, CuO, MgO) have been determined for a slow cooling rate from the melts under excess oxygen pressure. The stable glasses are situated near the SeO2 corner of the phase diagram. It has been established by IR spectroscopy that the main structural units, which form the network of SeO2-MoO3 glasses, are SeO3, SeO3 (Se = O), MoO6 and Mo2O5 groups. Several topological models are proposed for the structure, depending on the composition. On the basis of the structural peculiarities, conclusions are drawn about the glass-forming tendency in selenite systems.
