phosphate glass

Phosphate glasses are a category of oxide glasses that do not rely on silica as their primary component. These glasses, which include sodium phosphate glass, are generally composed of phosphates and borates. While not as commercially significant as silica-based glasses, they find niche applications in bioresorbable products like surgical mesh and time-release capsules. Sodium phosphate glasses, in particular, can be water-soluble and are used as sequestering agents in water treatment, deflocculating agents, and for protecting metals from corrosion. Hydroxylapatite, a phosphate mineral, can also form glassy masses. The production of glass ceramics can involve phosphorus pentoxide as a nucleating agent.1234
