Abstract: Formation processes and morphology of nanostructured glass ceramic materials containing finely dispersed lead sulfide crystalline phase has been studied by X-ray technique. The spatial ordering of PbS nanocrystals has been revealed which manifests itself by interference effects in X-ray scattering. We have ascertained that important morphology feature of the system is nearly monodisperse size distribution of nanocrystals.
