A glass series [xSiO₂[-y])·0.36ZnO·0.17Na₂O·0.05CaO (starting at x = 0.50, y = 0.08 TiO₂)] was formulated with TiO₂ substituting SiO₂. Each glass/silver-coated glass was characterized using X-ray diffraction, X-ray photoelectron spectroscopy (XPS), and scanning electron microscopy. Surface area analysis revealed significant changes after silver coating, 0.43-0.95 m²/g (control), to 0.53-1.85 m²/g (AU-1), and 0.20-1.11 m²/g (AU-2). Ion release from uncoated glasses included sodium (0.08 mg/L), calcium (0.07 mg/L), and zinc (0.008 mg/L), where silver-coated glasses presented 0.42 mg/L (silver), 0.33 mg/L (sodium), 0.02 mg/L (calcium), and 0.01 mg/L (zinc). Ag-coated glasses presented inhibition zones of 7.75 mm (control) compared to 1.04 mm (AU-2).
用 TiO₂ 替代 SiO₂ 来配方设计一个玻璃系列 [xSiO₂[-y])·0.36ZnO·0.17Na₂O·0.05CaO（起始时 x=0.50，y=0.08 TiO₂)]。采用 X 射线衍射、X 射线光电子能谱（XPS）和扫描电子显微镜对每一个玻璃/镀银玻璃进行了特性描述。表面面积分析表明，镀银后有显著的变化，从 0.43-0.95 m²/g（对照）变为 0.53-1.85 m²/g（AU-1）和 0.20-1.11 m²/g（AU-2）。未镀膜玻璃的离子释放包括钠（0.08 mg/L）、钙（0.07 mg/L）和锌（0.008 mg/L），而镀银玻璃的银释放量为 0.42 mg/L（银）、0.33 mg/L（钠）、0.02 mg/L（钙）和 0.01 mg/L（锌）。与对照（1.04 mm）相比，镀银玻璃的抑菌圈为 7.75 mm（AU-2）。
