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).
