摘要：

The fluorination of ZrO2 and HfO2 and the understanding of the fundamental chemistry of formation of ZrF4 and HfF4 in a fluorine atmosphere were investigated using a thermobalance. The fluorination of these species was performed to understand the chemical behavior of the tetrafluoride species of these metals. Thermogravimetrical analysis indicated that the formation of ZrF4/HfF4 is via the oxyfluorides. X-ray powder diffraction was used to confirm the results. (C) 2011 Elsevier B.V. All rights reserved.
