摘要:
A transparent cover glass for applications such as, but not limited to, touch screen devices that embody antimicrobial properties that include s being antibacterial, antifungal, and antiviral. The antimicrobial glasses contain nanoparticles of Cu or Cu2O on the surface of the glass. The antimicrobial glasses can further have a fluorosilane coating or other coating on the surface to make the glasses easy-to-clean. Also, glass surfaces having an antibacterial or antimicrobial surfaces and a protective coating on the surface that do not inhibit the antibacterial or antimicrobial properties of the glass are described. The disclosure is further directed to methods of making such articles.

摘要:
The present disclosure relates to fusion formable highly crystalline glass-ceramic articles whose composition lies within the SiO2—R2O3—Li2O/Na2O—TiO2 system and which contain a silicate crystalline phase comprised of lithium aluminosilicate (β-spodumene and/or β-quartz solid solution) lithium metasilicate and/or lithium disilicate. Additionally, these silicate-crystal containing glass-ceramics can exhibit varying Na2O to Li2O molar ratio extending from the surface to the bulk of the glass article, particularly a decreasing Li2O concentration and an increasing Na2O concentration from surface to bulk. According to a second embodiment, disclosed herein is a method for forming a silicate crystalline phase-containing glass ceramic.
