Abstract

The effect of spark plasma sintering (SPS) on the densification of TiO₂ ceramics was investigated using a nanocrystalline TiO₂ powder. A fully-dense TiO₂ specimen with an average grain size of ∼200 nm was obtained by SPS at 700 °C for 1 h. In contrast, a theoretical density specimen could only be obtained using conventional sintering above 900 °C for 1 h with an average grain size of 1-2 μm.
