Paper Abstract

We report here two studies relevant to these phenomena. Phase separation was unambiguously shown to occur in a ZrF4-based glass containing a small amount of PbF2 and prepared under a chloride-containing reactive atmosphere. Partial replacement of ZrF4 by HfF4 in a ZBLAN glass appears to improve the resistance to crystallization. The reason for this improvement seems to be a change in the crystalline phases and compositions first appearing on reheating.
