TaB₂ nanopowder has been prepared by the molten salt synthesis (MSS) technique. Nanowire-like TaB₂ nanopowder was successfully synthesized by reacting in the Ta₂O₅–MgB₂ system using KCl/NaCl as reaction media. The impact of the firing temperature (800°C to 1000°C), firing time (1 h to 4 h), and ratio of reactants to salt (1:0, 1:2, 1:5, and 1:10) on the preparation of the TaB₂ nanopowder was examined. The resultant powder samples were characterized by scanning electron microscopy (SEM), x-ray diffraction (XRD) analysis, transmission electron microscopy (TEM), high-resolution transmission electron microscopy (HRTEM), and surface area analysis (SAA). The results showed that the reaction involved in the formation of crystalline TaB₂ nanopowder could be completed successfully at 1000°C after 4 h of firing when the mass ratio of reactants to salt was 1:5. The resulting TaB₂ nanopowders exhibited nanowire-like morphology.

TaB ₂纳米粉已通过熔融盐合成（MSS）技术制备。以KCl / NaCl为反应介质，在Ta ₂ O ₅ -MgB ₂体系中反应，成功合成了纳米线状TaB ₂纳米粉。焙烧温度（800°C至1000°C），焙烧时间（1h至4h）以及反应物与盐的比例（1：0、1：2、1：5和1:10）的影响TaB ₂的制备检查了纳米粉。通过扫描电子显微镜（SEM），X射线衍射（XRD）分析，透射电子显微镜（TEM），高分辨率透射电子显微镜（HRTEM）和表面积分析（SAA）对所得粉末样品进行表征。结果表明，当反应物与盐的质量比为1：5时，焙烧4 h后，在1000℃下成功地完成了形成结晶TaB ₂纳米粉体的反应。所得的TaB ₂纳米粉体表现出纳米线状形态。
