Abstract

Abstract: TaB2 powders were synthesized by a molten‐salt assisted borothermal reduction method at 900°C‐1000°C in flowing argon using Ta2 O5 and amorphous B as starting materials. The results indicated that the presence of liquid phase, such as B2 O3 and NaCl/KCl, accelerated the mass transfer of reactant species and resulted in the complete finish of the reaction at low temperatures. The obtained TaB2 powders exhibited a flow‐like shape assembled from nanorods grow along [001] direction or c ‐axis. The morphology of the synthesized TaB2 powders could be tailored by the amount of B2 O3 or NaCl/KCl.
