Abstract

The crystallization of five ZrF4-based glasses has been investigated using powder X-ray diffraction and differential scanning calorimetry. The crystalline phase in Zr-Ba-La-Pb fluoride glass was found to beβ-BaZrF6. In other glasses the crystal phases could not be identified. Reversible polymorphic phase transformations occur in Zr-Ba-La-Li and Zr-Ba-La-Na fluoride glasses when heated to higher temperatures.
