Beschreibung
Zusammenfassung:	The invention discloses a high-temperature stable high-entropy ceramic material with excellent energy storage performance and a preparation method thereof.The preparation method comprises the steps that firstly, according to the molar ratio of (Ba0. 3Sr0. 7) TiO3, (Na0. 5Bi0. 5) TiO3 and (K0. 5Bi0. 5) TiO3, raw materials, absolute ethyl alcohol and zirconium oxide ballstone are subjected to ball milling and mixing, after drying and calcining are conducted respectively, (Ba0. 3Sr0. 7) TiO3 powder, (Na0. 5Bi0. 5) TiO3 powder and (K0. 5Bi0. 5) TiO3 powder are obtained, according to the molar ratio of (Ba0. 12Sr0. 28K0. 3xBi0. 3Nax) TiO3 (x is larger than or equal to 0.125 and smaller than or equal to 0.2 The preparation method comprises the following steps: drying the raw materials to obtain final material powder, pre-pressing the material powder through a mold, carrying out cold isostatic pressing, and sintering at 1220-1250 DEG C for 4 hours to obtain the high-entropy perovskite ceramic, the high-entropy perov
