    Abstract: A method of treating a substrate is provided that includes the steps: submersing a substrate having an outer region containing a plurality of divalent exchangeable ions in a bath that comprises a polar solvent and a plurality of divalent ion-exchanging ions, the substrate comprising a glass, glass-ceramic or ceramic; pressurizing the bath to a predetermined pressure substantially above ambient pressure; and heating the bath to a predetermined temperature above ambient temperature. The method also includes a step of treating the substrate for a predetermined ion-exchange duration such that a portion of the plurality of divalent exchangeable ions is exchanged with a portion of the divalent ion-exchanging ions. In addition, the step of treating the substrate results in a greater number of divalent ion-exchanging ions entering the substrate than divalent exchangeable ions exiting the substrate.

    Abstract: Embodiments of antimicrobial materials are provided. In one or more embodiments, the antimicrobial materials include an inorganic substrate including a surface portion surrounding an internal portion and an antimicrobial agent disposed on any one or more of the surface portion and the internal portion. In some embodiments, the inorganic substrate included alkali and at least a portion of the alkali is present on the surface portion. In another embodiment the antimicrobial agent is infused into the substrate. In some instances, non-alkali components present in the substrate are replaced with the antimicrobial agent. In some embodiments, anions in the substrate are replaced with the antimicrobial agent. Compositions including the antimicrobial materials are disclosed and methods for making the antimicrobial materials and compositions are also provided.

    Abstract: A method of treating a substrate in a pressure vessel that includes the steps: preparing an ion-exchange bath with a bath composition that comprises a polar solvent and a plurality of ion-exchanging ions in a vessel; submersing a substrate having an outer region containing a plurality of exchangeable ions in the bath; pressurizing the bath in the vessel to a predetermined pressure substantially above ambient pressure; heating the bath in the vessel to a predetermined temperature; and treating the substrate for a predetermined ion-exchange duration at the predetermined pressure and temperature such that a portion of the plurality of exchangeable ions is exchanged with a portion of the ion-exchanging ions. The substrate can consist essentially of a glass, glass-ceramic or ceramic substrate composition, and the predetermined ion-exchange duration, temperature and pressure can each be selected based at least in part on the substrate composition and the bath composition.
