Paper Abstract

In this paper the glass-forming ability in the system of RF2-AlF3-YF3 was studied. The relationships between some physical properties, including refractive index, density, characteristic temperatures and viscosity, and chemical composition were reported. The crystallization kinetics of glass in the melt-cooling and glass-reheating process were investigated. The experimental results show that this fluoroaluminate glass is characterized by a widely transparent region from 0.2 to 7 um, a low refractive index, a high Abbe's vaille and other good physical and chemical properties. Especially this glass has much better chemical durability against water and higher mechanical strength comparing to the fluorozirconate glasses.
