Powder synthesis is crucial for achieving the densification and facilitating widespread applications of high entropy carbide (HEC). Specifically, the production of fine particle‐size powders is essential to enhance the densification of HECs. Consequently, this paper proposes the molten salt method for synthesizing HEC powders. The synthesis process successfully yielded (Ta Nb Ti V) C powders with a particle size of only 0.44 µm at 1400°C, exhibiting a uniform distribution of each element. Subsequent densification of (Ta Nb Ti V) C within the 1700–1900°C temperature range was carried out using spark plasma sintering. It was observed that as the densification temperature increased, the densification and mechanical properties of HEC significantly improved. This study presents innovative ideas for the preparation of HEC at lower temperatures.

低温熔盐合成(Ta Nb Ti V) C粉末对高熵碳化物陶瓷致密化和性能的影响

粉末合成对于实现高熵碳化物（HEC）的致密​​化和促进广泛应用至关重要。具体而言，细粒度粉末的生产对于增强 HEC 的致密化至关重要。因此，本文提出熔盐法合成HEC粉末。该合成过程在1400°C下成功生成了(Ta Nb Ti V) C粉末，其粒径仅为0.44 µm，且各元素分布均匀。随后使用放电等离子烧结在 1700–1900°C 温度范围内进行 (Ta Nb Ti V) C 致密化。结果表明，随着致密化温度的升高，HEC 的致密化和机械性能显着提高。这项研究提出了在较低温度下制备 HEC 的创新思路。
