| Abstract: | Dense TiB ceramics (99.6% of theoretical) with a grain size of ～5 µm have been fabricated by reaction hot pressing of TiB2 and titanium for 2 h at 1900°C and 28.5 MPa. The TiB ceramics exhibit a fracture toughness ( KIC ) of 4.5 MPa·m1/2 and a bending strength (sigmab) of 360 MPa. Electrical resistivity (rho) is 3.4 × 10-7 Omega·m at room temperature. |
