Abstract

The structure of oxide melts based on nanoformations (compacted regular clusters) located in a discharged quasi-gas matrix has been proposed. Clusters are formed when crystals melt. The nearest interatomic distances and coordination in the clusters are mostly the same as in the crystals before melting. Compacted clusters are located inside a continuous discharged medium (quasi-gas matrix). The X-ray scattering on the atoms of the oxide melt two parts. The principal contribution of X-ray scattering is due to the scattering from the cluster component of the melt. The diffuse scattering from the quasi-gas matrix makes a relatively weak contribution to the overall diffraction pattern.
