Lithium Zinc Phosphate (LZP) glasses are compositionally tunable materials with potential applications in biomaterials, optics, and waste vitrification. Previous research on a series of 40 mol% P2O5 glasses showed increased density, refractive index, and thermal stability with higher Li2O content. A series of 45 mol% P2O5 glass showed increased polymerization, and thus lower dissolution was expected, but limited durability data existed. For this project, static dissolution tests in DI water were performed on LZ45P glasses. Powders (150-300 microns) were immersed at 20 C and sampled at 1, 4, 8, 16, and 24 hours. Dissolution behavior was assessed through mass loss measurements and pH monitoring of the leachate. Initial results suggest slower network breakdown in LZ45P compared to LZ40P, consistent with higher P2O5 content, and mixed Li-Zn compositions appear to further stabilize dissolution behavior. |
