| Abstract: | Nucleation rates were measured in a ZrF4–BaF2–NaF–LaF3–AlF3 glass (ZBLAN) using an optical technique. The results were compared with a similar glass having a slightly different composition. The difference in the nucleation rate is explained by classical nucleation theory using calculated free-energy differences between the ZBLAN liquid and the BaZrF6 crystal, which is found as the precipitating phase. |
