High-entropy boride nano-powder as well as preparation method and application thereof
The invention discloses high-entropy boride nano powder as well as a preparation method and application thereof. The high-entropy boride nano powder is prepared from HfCl4, ZrCl4, TaCl5, NbCl5, NaBH4, LiCl and KCl through sintering, water washing and alcohol washing. The preparation method of the high-entropy boride nano powder comprises the following steps of 1, mixing and grinding HfCl4, ZrCl4, TaCl5, NbCl5, NaBH4, LiCl and KCl, and obtaining mixed powder; and 2) sintering the mixed powder in a protective atmosphere at the temperature of 800-900 DEG C, washing with water, washing with alcohol, and drying to obtain the high-entropy boride nano powder. The high-entropy boride nano powder is small in particle size, high in purity, uniform in component, simple in preparation process, low in equipment requirement, low in sintering temperature, free of pollution and suitable for large-scale production and application.
本发明公开了一种高熵硼化物纳米粉体及其制备方法和应用。本发明的高熵硼化物纳米粉体由HfCl4、ZrCl4、TaCl5、NbCl5、NaBH4、LiCl和KCl经过烧结、水洗和醇洗制成，其制备方法包括以下步骤：1)将HfCl4、ZrCl4、TaCl5、NbCl5、NaBH4、LiCl和KCl混合进行研磨，得到混合粉体；2)将混合粉体置于保护气氛中800℃～900℃进行烧结，再进行水洗、醇洗和干燥，即得高熵硼化物纳米粉体。本发明的高熵硼化物纳米粉体粒径细小、纯度高、成分均匀，且制备过程简单、对设备要求低、烧结温度低、无污染，适合进行大规模生产应用。
