TaB2 powders were synthesized by a molten-salt assisted borothermal reduction method at 900–1000 °C in flowing argon using Ta2O5 and amorphous B as starting materials. The results indicated that the presence of liquid phase, such as B2O3 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 B2O3 or NaCl/KCl. This article is protected by copyright. All rights reserved.

熔盐辅助硼热还原低温合成TaB2纳米棒

TaB2 粉末是通过熔盐辅助硼热还原法在 900-1000°C 下在流动的氩气中使用 Ta2O5 和无定形 B 作为起始材料合成的。结果表明，液相的存在，如 B2O3 和 NaCl/KCl，加速了反应物物质的传质，导致反应在低温下完全完成。获得的 TaB2 粉末表现出由沿 [001] 方向或 c 轴生长的纳米棒组装而成的流动状形状。合成的 TaB2 粉末的形态可以通过 B2O3 或 NaCl/KCl 的量来定制。本文受版权保护。版权所有。
