Abstract
Vickers hardness of nanocrystalline (N‐) TiO2 was measured in the temperature range 25° to 1200°C and it was compared with that of polycrystalline (P‐) TiO2 in the same temperature range. N‐TiO2 showed a lower hardness than P‐TiO2 at temperatures up to 800°C which resulted in the lack of indentation crack traces for N‐TiO2 presumably implying more plasticity.
