Resumo

Hafnium diboride nano- and microcrystals are studied by high-temperature X-ray diffraction in the temperature range of 300–1500 K. HfB2 nanocrystals are found to have a greater thermal expansion coefficient than HfB2 microcrystals. The thermal expansion of HfB2 is found to be anisotropic with respect to the unit cell axes.
