Abstract

The present invention relates to the technical field of high performance ceramics, and in particular to a preparation method for fluorite-type high entropy ceramics. By calcining the high entropy ceramic powder, the fluorite-type high entropy ceramic is obtained. The preparation method of the high entropy ceramic powder includes the following steps: dispersing the transition metal salt with the rare earth metal salt and substance A in water to obtain a mixed solution; adding a precipitant dropwise to the mixed solution until the precipitation is complete, centrifuging after standing, washing and drying the resulting precipitate, grinding, and obtaining the high entropy ceramic powder. The present invention uses co-precipitation method to prepare high entropy ceramic precursor powder (high entropy ceramic powder), which requires simple experimental equipment, easy to operate and convenient for scale production, and at the same time can significantly reduce the sintering temperature of high entropy ceramic powder, and can achieve rapid sintering of ceramics in the temperature range of 1000-1400 degrees Celsius to obtain high entropy ceramics with fluorite structure.
