High-entropy oxide ceramic and preparation method thereof
The invention relates to the technical field of preparation of inorganic non-metallic materials, in particular to a preparation method of high-entropy oxide ceramics, which comprises the following steps: ball-milling and mixing Al2O3 powder, ZrO2 powder, NiO powder, TiO2 powder, CuO powder, Y2O3 powder and CeO2 powder in a molar ratio of 0.4: 0.1: 0.1: 0.1: 0.1: 0.1: 0.1 to 0.4 to obtain mixed powder; drying, grinding and sieving the mixed powder, and performing compression molding under 30-70MPa to obtain a blank body; and carrying out microwave sintering on the blank body at 1150-1350 DEG C to obtain the high-entropy oxide ceramic. The high-entropy oxide ceramic prepared by the preparation method disclosed by the invention has relatively high hardness and compactness and relatively good fracture toughness.
