摘要：

The radial distribution analysis of liquid Sb2Se3 at 670, 720 and 770°C is carried out by the neutron diffraction method. A small but apparent maximum is found at K = 1.2 A ̊-1 in the structure factor. The interatomic distance and the coordination number are 2.74 Å and 2.84 respectively, at 670°C. These results suggest that intramolecular bonds in the crystalline Sb2Se3 remain unbroken in the liquid state. The general feature of the structure factor and the distribution function for liquid Sb2Se3 is similar to that for the amorphous state. However, it is clear that the liquid phase tends to have a similar atomic arrangement to that of liquid tellurium. © 1978.
