摘要：
Submicron tungsten diboride (WB2) powder was successfully synthesized with the ratio of WO3:B4C:C = 2:1.1:5. The effects of carbon sources (carbon black or graphite) and heat treatment temperatures (1100, 1200, 1300 degrees C) on the phase composition and microstructure of the as-synthesized WB2 powder samples were studied. The results showed that ultrafine WB2 powders with oxygen content of 1.65 wt% and 2.04 wt% were obtained by carbon black and graphite at 1300 degrees C, respectively. The relatively density of the as-sintered WB2 samples achieve similar to 91 % and similar to 87 % without any kind of sintering additive after spark plasma sintering at 1500 degrees C under 30 MPa for 10 min. The formation mechanism of the WB2 powders synthesized by boro/carbothermal reduction was proposed and verified by thermodynamic calculation according to the phases present in the powder synthesized at different temperatures.
