(Hf < 0.25 > Ti < 0.25 > Zr < 0.25 > W < 0.25 >) N high-entropy ceramic powder and preparation method thereof
The invention discloses (Hf < 0.25 > Ti < 0.25 > Zr < 0.25 > W < 0.25 >) N high-entropy ceramic powder and a preparation method thereof. The invention aims to solve the problems of high requirements and low yield of the existing high-entropy ceramic preparation equipment. The method comprises the following steps: taking one or two kinds of mixed powder of KCl or NaCl; carrying out ball milling onZrO2, TiO2, HfO2 and WO3 powder and KCl or NaCl powder to obtain mixed powder; carrying out heat treatment on the mixed powder in a protective atmosphere; and washing the obtained powder with an HCl solution, and drying the washed powder to obtain the high-purity (Hf < 0.25 > Ti < 0.25 > Zr < 0.25 > W < 0.25 >) N high-entropy ceramic powder. The preparation of the (Hf < 0.25 > Ti < 0.25 > Zr < 0.25 > W < 0.25 >)N high-entropy ceramic powder provided by the invention has the advantages of low preparation temperature, low equipment requirement, high yield and the like, and has potential application value in the fields of energy, aviation and spaceflight.
本发明公开了一种（HfTiZrW）N高熵陶瓷粉体及其制备方法。本发明的目的是为解决现有制备高熵陶瓷设备要求高、产率低的难题。该方法包括：取KCl或NaCl一种或两种混合粉体；将ZrO、TiO、HfO及WO的粉体与KCl或NaCl粉体球磨，获得混合粉体；将混合粉体在在保护气氛下热处理；将所得的粉体用HCl溶液洗涤，烘干，得到高纯（HfTiZrW）N高熵陶瓷粉体。本发明提供的（HfTiZrW）N高熵陶瓷粉体的制备具有制备温度低、设备要求低及产率高等优点，在能源、航空及航天领域具有潜在的应用价值。
