Abstract

Network-forming structural motifs such as SiO4 tetrahedra play a key role in governing the physical and chemical properties of disordered oxide materials, which range from photonic glasses to the fluids in planetary interiors. Here we show that the coordination number of these motifs, which has a profound effect on the connectivity of an atomic network [1], can be rationalized in terms of the oxygen-packing fraction over an extensive pressure and temperature range.
