Abstract:

The physical properties and alkaline corrosion resistant properties of calcium-ironphosphate glasses were studied. Iron addition decreases the thermal expansion coefficient and increases the Young’s modulus in comparison with the addition of calcium oxide. Glass dissolution behavior in alkaline solutions was studied by weight loss experiments, x-ray diffraction, and analytical scanning electron microscopy. The results show that the dissolution rate decreases when the phosphate chain length decreases. Calcium oxide can improve the glass durability in high pH solutions in comparison with ferric oxide. Phase equilibrium modeling was used to explain the formation of corrosion products, including hydroxyapatite. /Abstract from report summary page/
