Thermal Expansion of HfO 2 and ZrO 2
The thermal expansion of a low symmetry crystal can be much more interesting than the lattice parameter expansion would suggest. Here, the complete thermal expansion tensors for monoclinic and tetragonal phases of ZrO 2 and HfO 2 have been measured in air, by high‐resolution, high‐temperature X ‐ray...

Summary: | The thermal expansion of a low symmetry crystal can be much more interesting than the lattice parameter expansion would suggest. Here, the complete thermal expansion tensors for monoclinic and tetragonal phases of
ZrO
2
and
HfO
2
have been measured in air, by high‐resolution, high‐temperature
X
‐ray diffraction. These results reveal the highly anisotropic nature of thermal expansion in the monoclinic phase as well as a cooperative movement of ions and the existence of a zero thermal expansion plane. |
