Ternary layered MAX-phase ceramics have the comprehensive characteristics of ceramics. Metals are a type of machinable structural ceramic material. They have good application prospects in high temperature, irradiation, high stress, and other environments. Ti₂AlC, V₂AlC, Nb₂AlC, Cr₂AlC, and Ta₂AlC belong to the M₂AlC MAX phase. And they are typical representatives of ternary layered ceramics.

Our customers are on the premise of ensuring the proportion of each element in the M₂AIC MAX-phase. We hope to introduce a high entropy effect into MAX-phase ceramics by changing the number of transition elements M. To improve the comprehensive performance of MAX-phase ceramics. Two different formulations of metal carbide/aluminum/transition metal mixed powder. And mix MAX-phase powder used as raw materials. Synthesize the three high entropy ceramic materials, (Ti_1/3V_1/3Nb_1/3)₂AIC, (Ti_0.25V_0.25Nb_0.25Cr_0.25)₂AIC and (Ti_0.2V_0.2Nb_0.2Cr_0.2Ta_0.2)2AlC, by fast hot pressing sintering furnace CEN-FHP-808 in our open laboratory. The effects of the batching scheme and sintering temperature on the microstructure and properties of the three high entropy MAX phase ceramic materials were studied.
