Purification and Analytical Techniques for Fluoride Glass Starting Materials

FeCl3 behavior in acetonitrile: structures of [FeCl2(CH3CN)4][FeCl4] and [AlCl(CH3CN)5][FeCl4]2.CH3CN

“…Very pure starting fluorides are required for fluoride glasses of high optical performance (France, Carter, Moore & Williams, 1987); new ways of synthesizing such pure fluorides have been sought for several years (Folweiler & Pink;Guery & Jacoboni, 1988). A previous study of the behavior of zirconium chloride in acetonitrile led to the determination of the crystal structure of ZrC14.2CHaCN (Guery, Leblanc & Jacoboni, 1989).…”
