ZrO2-CNT composite production through reducing atmosphere

Zirconia (ZrO2) is a well-known and widely used ceramic in engineering applications and is even termed as ‘ceramic steel’ in its tetragonal stabilised phase (TZP). However, even the tetragonal zirconia has some issues with low fracture toughness and attempts to enhance its toughness have been resear...
