The aim of this study is to produce and characterize glass materials, which have an enhanced antibacterial property by the conventional melting method. Container glass compositions including different amounts of zinc oxide (ZnO) (5.0, 7.5, and 10.0%) were prepared and melted to be able to obtain the antibacterial glass. The Release and antibacterial tests, which were performed after the melting process, showed that the glass doped with 5% ZnO was the most appropriate composition according to test results (99.82% inactivation) and its raw materials' costs. Physical, thermal, and mechanical properties such as thermal expansion coefficient (86.1 × 10/°C), density (2.523 g/cm), refractive index (1.5191), hardness (596 kg/mm), and elastic modulus (5.84 GPa) of the glass doped with 5% ZnO were determined, and the results showed that the obtained antibacterial glass sample is suitable to be used as a glass container. HighTemperature 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. This antibacterial glass can be a remarkable product for the pharmaceutical and food industries.
本研究的目的是通过传统熔融法制备具有增强抗菌性能的玻璃材料并对其进行表征。制备了包含不同含量氧化锌（ZnO）（5.0%、7.5%和10.0%）的容器玻璃组合物，并将其熔融以获得抗菌玻璃。在熔融过程之后进行的释放和抗菌测试表明，根据测试结果（99.82%的失活率）及其原材料成本，掺杂5% ZnO的玻璃是最合适的组合物。测定了掺杂5% ZnO的玻璃的物理、热学和力学性能，如热膨胀系数（86.1×10⁻⁶/°C）、密度（2.523 g/cm³）、折射率（1.5191）、硬度（596 kg/mm²）和弹性模量（5.84 GPa），结果表明所获得的抗菌玻璃样品适合用作玻璃容器。对所制备的抗菌玻璃组合物进行了高温熔融观察系统研究，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。这种抗菌玻璃对于制药和食品行业而言可能是一种卓越的产品。
