Structure of liquid compound PbTe

Chemical PbTe compound is synthesized by fusion of especially pure components in tubes pumped out to high vacuum. It is noted, that after PbTe fusion a certain part of atoms preserves the close order, typical of crystal compound, and the rest form groups with a denser atom distribution. In the first case the bound is mainly covalent, in the second-metal. Mixed bonds lead to the production of local groups with different atomic distribution geometry, determined by the number of the nearest neighbours and by the most probable interatomic distances
