This study was aimed to produce and characterize the first commercial glass materials with enhanced antibacterial property using conventional melting method. For this purpose, typical container glass composition that contains some specific metal ions, such as silver, strontium, and copper, was used to obtain antibacterial glass samples using classical melting method. After the melting process, antibacterial tests and migration tests were applied to the glasses, and it was found that the glass doped with 2% AgO was the best composition. X-rays diffractometer (XRD), thermal expansion coefficient, density, refractive index, hardness, and elastic module results showed that the glass doped with 2% AgO was a suitable material as a container glass. High Temperature Melting Observation System studies were performed on the produced antibacterial glass composition, and it was found that the antibacterial glass can be produced in soda lime glass furnaces without changing any furnace design and production parameters. As a result of the characterization studies, it was concluded that the produced container glass doped with silver can be a good candidate for food and pharmaceutical products where bacterial growth is absolutely undesirable.
本研究旨在采用传统熔融法制备并表征首批具有增强抗菌性能的商用玻璃材料。为此，使用含有银、锶和铜等特定金属离子的典型容器玻璃成分，通过经典熔融法获得抗菌玻璃样品。熔融过程完成后，对玻璃进行了抗菌测试和迁移测试，结果发现掺杂2% AgO的玻璃是最佳成分。X射线衍射仪（XRD）、热膨胀系数、密度、折射率、硬度和弹性模量结果表明，掺杂2% AgO的玻璃是一种适合用作容器玻璃的材料。对所制备的抗菌玻璃成分进行了高温熔融观察系统研究，结果发现，无需改变任何熔炉设计和生产参数，即可在钠钙玻璃熔炉中生产抗菌玻璃。表征研究结果表明，所制备的掺杂银的容器玻璃有望成为食品和药品的优质包装材料，因为细菌在这些产品中生长是绝对不可取的。
