Physicochemical properties of ZrF4-BaF2-LnF3 glasses (Ln=Y or rare-earth elements)

The influence of lanthanoid fluorides on physicochemical properties of fluorozirconate glasses has been examined on 60ZrF4 · 30BaF2 · 10LnF3 glasses (Ln=Y, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Er, Tm, Yb or Lu). Physicochemical properties such as ion packing, hardness, molecular refraction, thermal stability and fluoride-ion conduction have been evaluated on the glasses by the density, refractive index, differential thermal analysis, thermomechanical analysis, Vickers hardness and electrical conductivity measurements. The variation of these properties with lanthanoid species and the relationships between them have been discussed to characterize lanthanoid fluoride-containing fluorozirconate glasses.
