Abstract Scope TiB2 ceramics belong to a group of ultrahigh temperature ceramics which are known as refractory transition metal borides, carbides and nitrides. Owing to their excellent properties such as high melting temperature (3225C), high hardness, high elastic modulus, high thermal conductivity, good thermal shock resistance, chemical stability and good wear resistance, TiB2 ceramics are suitable for numerous applications such as cutting tools, armour materials, wear-resistant parts and cathode material in Hall–Heroult aluminum electrolysis cells. Nonetheless, densification of monolithic TiB2 ceramics are limited because of its high melting point, low self-diffusion coefficient and covalent bonding. In this study, TiB2 ceramics with various amounts of Ti (3, 5, 7 w.t.%) as a sintering aid were produced with spark plasma sintering (SPS) method in the temperature range between 1600C-1800C. The effect of titanium addition on densification, microstructure and mechanical properties of as-sintered samples will be examined.
