Beschreibung:
TaB 2 powders were synthesized by a molten-salt assisted borothermal reduction method at 900–1000 °C in flowing argon using Ta 2 O 5 and amorphous B as starting materials. The results indicated that the presence of liquid phase, such as B 2 O 3 and NaCl/KCl, accelerated the mass transfer of reactant species and resulted in the complete finish of the reaction at low temperatures. The obtained TaB 2 powders exhibited a flow-like shape assembled from nanorods grow along [001] direction or c-axis. The morphology of the synthesized TaB 2 powders could be tailored by the amount of B 2 O 3 or NaCl/KCl. This article is protected by copyright. All rights reserved.
