Abstract

Network structure and polyamorphism of borosilicate melts are investigated by molecular dynamics simulation. The local structure of elements is investigated via radial distribution function, coordinatio n num5er distribution. The topology of tetrahedral and and triangular is analyzed via O-T-O bond angle and T-O bond length distribution (where T = Si, B). Glassy network structure is investigated via distribution of linkages Si-O-Si, B-O-Si and B-O-B and (Q is and n is the number of bridging oxygen (BO) in units). Specially, the polyamorphism as well as structural and compositional heterogeneities are also presented and discussed in detail.
