Novel oxyfluorophosphate glasses and glass-ceramics
Abstract
Effect of CaF<sub>2</sub> addition at the expense of CaO on the thermal, physical, optical and structural properties of glasses in the NaPO<sub>3</sub>–CaOsystem was studied. The glasses were prepared by the conventional meltquenching method. For each glass, the thermal properties were studied bydifferential thermal analysis (DTA) and the optical properties byUV–Vis-NIR spectroscopy. The changes in the glass structure induced bythe progressive replacement of CaO by CaF<sub>2</sub> were investigatedusing IR and Raman spectroscopies. The glasses were heat treated at20 °C above their respective glass transition temperature for 17 h toform nuclei and then at their peak crystallization temperature for 1 hto grow the nuclei into crystals. An increase in the CaF<sub>2</sub> content increased the polymerization of the phosphate network leading toshift of the band gap to lower wavelength and reduced thecrystallization tendency of the glasses. At least two crystalline phasesprecipitated in all the investigated glasses, the composition of whichdepended on the CaF<sub>2</sub> content. Finally, bulk crystallization was suspected to occur in the oxyfluorophosphate glasses.
