Abstract As a new and important problem in condensed state physics, the discontinuous structural change of liquid with temperature rising is testified by various experimental technologies. However, fractal language has been more and more frequently used to describe some disordered physical systems except liquid alloys. This paper has successfully implemented fractal ideas to observe fractal structures in liquid In-Sn alloy and considers its fractal dimension as a physical quantity sensitive to structure. Moreover, from the fractal viewpoint, the mutation of the fractal dimension has indicated once again that the liquid structure change discontinuously with temperature rising.
