Structural Investigation And Properties Of Gallium Zinc Phosphate Glasses

Phosphate glasses, especially glasses based on zinc-phosphate, are being intensively studied during recent years because they provide some unique physical properties compared to silicate glasses, such as low melting temperature, high coefficient of thermal expansion and low optical dispersion. The introduction of various metal oxides results in variability of their physical and chemical properties, gallium trioxide has received attention because of improving chemical durability and of antibacterial properties. The aim of this work was to study the effect of substitution of zinc by gallium on some physicochemical properties of phosphate glasses, as well as on their structure.
