TiB₂+EuB₆ ceramic samples with different EuB₆ contents were fabricated using hot-pressing technique. The introduction of EuB₆ promoted the sinterability, fracture toughness and oxidation resistance of TiB₂. 98.7% TD achieved by adding 2.5% EuB₆ to TiB₂ by hot pressing at a relatively low temperature of 1750°C, 35 MPa, 1h. Formation of complete solid solution of TiB₂+EuB₆ observed for all the samples by XRD, EDS and EBSD. Hardness of all samples is measured in the range of 24-27 GPa ~50% higher fracture toughness value of 5.2 MPa m^1/2 was obtained in the 2.5% EuB₆ contained sample compared to monolithic TiB₂. Enhancement of oxidation resistance of TiB₂ was observed by EuB₆ addition due to the formation of EuBO₃ and Eu2O₃. Oxidized cross section of TiB₂+EuB₆ sample was measured as 340µm, which is ~35% less than that of monolithic TiB2(520µm), after oxidation at 1400°C for 8h.
