Studying the effect of temperature on the structure, structural and dynamic heterogeneity of liquid silica

Abstract

The authors performed a molecular dynamics simulation to survey the structural and dynamic transition in liquid silica. In detail, research results on the radial distribution function, the coordination number, the characteristics of the domain and average energy per atom showed that silica undergoes three different structural regions when the temperature increases from 2000 to 6000 K. The structural transition occurred most strongly at the temperature range of 4500-5000 K...
