概要
- 論文の詳細を見る
A PbF_2-AlF_3 fluoride system has been vitrified in the shape of a ribbon using roller quenching over the composition range 30 to 60 mol% AlF_3. The infrared absorption edge of the glass originates from the absorption band of AlF_3 in PbF_2 around a wavelength of 18 μm. The crystallization temperature is determined by DTA to be 280-350℃, and increases with increasing AlF_3 content in the glass. The activation energy of crystallization is found to be about 80 kcal/mol for the PbF_2-30 mol% AlF_3 glass.
