Structure and dissolution of silicophosphate glass.

ABSTRACT: P₂O₅-SiO₂-Na₂O-CaO glasses are promising therapeutic ion-releasing materials. Herein, we investigated the state of silicon (Si) in P₂O₅-SiO₂-Na₂O-CaO glass using a model with a composition of 55.0P₂O₅-21.3SiO₂-23.7Na₂O (mol%), incorporating a six-fold-coordinated silicon structure (^[6]Si). The model was constructed using a classical molecular dynamics method and relaxed using the first-principles method. Further, we experimentally prepared glasses, substituting Na₂O for CaO, to investigate the dissolution of glass with varying ^[6]Si and PO₄ tetrahedra (Q _P ⁿ ) distributions (n</
