Abstract

Zirconium tetrafluoride (ZrF4) is the major constituent of many heavy metal fluoride glasses of technological interest. Five samples of commercially available “zirconium fluoride” were analyzed to determine their exact nature. Two samples were found to be anhydrous β-ZrF4, one was found to be α-ZrF4, one was zirconium tetrafluoride monohydrate (ZrF4 · H2O), and the final sample was identified as a hydrated amorphous phase of ZrF4. The behavior of these samples on heating was investigated with particular interest in the removal of water and the loss of fluorine from the hydrated materials. Infrared spectroscopy, x-ray diffractometry, thermogravimetric analysis, and differential scanning calorimetry were used in this investigation.
