A modified random network model for P₂O₅-Na₂O-Al₂O₃-SiO₂ glass studied by molecular dynamics simulations.

49 Although the percentage of Si–O–Si connection decreases with increased P content, DPC SiSi has an increasing trend, indicating that P obviously improves the priority of Si–O–Si linkage, especially for LAP compositions, suggesting the formation of separated silicon–oxygen rich regions, which could induce the emerging of cristobalite (SiO 2 ) crystals after heat treating. 50 Such complex bonding geometries might
