Abstract
In this study, quaternary phosphate-based sol-gel derived glasses were synthesized from a P₂O₅-CaO-Na₂O-TiO₂ system with a high TiO₂ content of up to 50 mol%. The sol-gel method was chosen because incorporating a high percentage of titanium into a phosphate network via traditional melt-quench methods is non-trivial. The structure and thermal..... More
