Özet:

 


The
present study reports the in-situ synthesis of hybrid powders containing
vanadium borides (VB2, V3B4 and V2B3)
and vanadium carbide (VC) using powder metallurgy methods. VB2-V3B4-V2B3/VC
hybrid powders were synthesized from V2O5,
B2O3 and
C powder blends via a carbothermal reduction route assisted by mechanical
milling. Powder blends were mechanically milled up to 5 h in a high-energy ball
mill. The milling process reduced the crystallite size, increased the
uniformity of the particle distribution and hence increased the reactivity of
the starting powders. As-blended and milled powders were annealed at different
temperatures (1400, 1500 and 1600°C) for 12 h to investigate the probability of
achieving vanadium boride and carbide phases simultaneously. Annealed powders
were characterized using X-ray diffractometer (XRD), scanning electron
microscope/energy dispersive spectrometer (SEM/EDS) and particle size analyzer.
In case of using annealing temperature of 1400°C, VB2-V3B4-V2B3/VC
hybrid powders were obtained with an amount of unreacted V2O5.
Annealing temperatures of 1500 and 1600°C resulted in the formation of VB2,
V3B4, V2B3
and VC phases. Milling affected the weight percentages of the phases as well as
the type of major boride phase.
