Thermal stability and crystallization behavior of TiO2 doped ZBLAN glasses
ZBLAN glasses with the composition (in mol%) of (100−x)(53 ZrF4+19 BaF2+5LaF3+3AlF3+20NaF)+xTiO2 (x=0, 1.0 and 2.0mol%) were prepared using a conventional melting technique in dry nitrogen atmosphere. The thermal stability, glass-forming ability, and crystallization kinetics of the ZBLAN system as a...

Summary: | ZBLAN glasses with the composition (in mol%) of (100−x)(53 ZrF4+19 BaF2+5LaF3+3AlF3+20NaF)+xTiO2 (x=0, 1.0 and 2.0mol%) were prepared using a conventional melting technique in dry nitrogen atmosphere. The thermal stability, glass-forming ability, and crystallization kinetics of the ZBLAN system as a function of the TiO2 concentrations were investigated by Differential Scanning Calorimetry (DSC). Also, the crystalline phases were determined by X-ray Diffraction (XRD). Our study indicates that adding TiO2 in a fluoride system improves the thermal parameters of the glass, which is interesting for applications as optical fiber.
► TiO2 was incorporated in fluoride ZBLAN glass under dry nitrogen atmosphere. ► Glass thermal stability and Tg increase for high content of TiO2. ► The 2.0 mol% of TiO2-doped ZBLAN glass exhibits greatest glass-forming ability. |
