Abstract

TiB₂ powders were synthesized from carbon coated titanium dioxide (TiO₂) precursors at 1500°C for 2 hours with argon flowing. X-ray diffraction (XRD) and scanning electron microscope (SEM) were used to characterize the produced powders. Phase evolutions were investigated based on XRD patterns. Synthesized TiB₂ powders have the advantages of pure and single phase, fine particle size, regular shape, and loose agglomeration. Densifications were conducted from produced TiB₂ powders with cobalt content as 3 wt. %, 10 wt. % and 20 wt. % at 1500°C in argon through presureless sintering. All samples reached higher than 98% theoretical density (TD). Consequently, sintered samples show excellent mechanical properties including elastics modulus (469-523 GPa), Vickers hardness (20.2-28.1 GPa), and fracture toughness (7-8.7 MPa*m^1/2).
