High-entropy ceramic powder and preparation method thereof
The invention relates to high-entropy ceramic powder and a preparation method thereof. The preparation method comprises the following steps: (1) preparing transition metal carbide powder and Si powder into a mixture, and carrying out ball-milling mixing to obtain mixed powder or mixed powder suspension to be treated; the ratio of the total mass of the transition metal carbide powder to the mass of the Si powder is (5-30): 1; (2) carrying out intermediate treatment on the to-be-treated mixed powder or mixed powder suspension obtained in the step (1) to obtain to-be-burnt mixed powder; and (3) carrying out heat treatment on the mixed powder to be burnt obtained in the step (2) in a vacuum or inert atmosphere to obtain the single-phase entropy stabilized carbide ceramic powder, and (4) crushing and sieving the single-phase entropy-stabilized carbide ceramic powder obtained in the step (3) to obtain the entropy-stabilized carbide ceramic powder which is uniformly dispersed and has fine particles.
本发明涉及一种高熵陶瓷粉体及其制备方法。所述制备方法包括：(1)将过渡金属碳化物粉体和Si粉配成混合料，进行球磨混合，得到待处理的混合粉体或混合粉体悬浊液；所述过渡金属碳化物粉体的总质量与Si粉的质量比为(5～30)：1；(2)将步骤(1)得到的待处理混合粉体或混合粉体悬浊液进行中间处理，得到待烧混合粉体；(3)将步骤(2)得到的待烧混合粉体在真空或惰性气氛下热处理，获得单相熵稳定碳化物陶瓷粉体；(4)将步骤(3)获得的单相熵稳定碳化物陶瓷粉体破碎、过筛，得到分散均匀、颗粒细小的熵稳定碳化物陶瓷粉体。
