Method for high-entropy stabilization of cubic zirconia and tetragonal zirconia phase structures

The invention discloses a method for high-entropy stabilization of cubic zirconia and tetragonal zirconia phase structures, which comprises the following steps: 1) firstly, calculating an entropy value and preparing non-water-based ceramic slurry, calculating a theoretical entropy value of the zirconia ceramic by using an ion mixed entropy formula, adding a dispersing agent and a binding agent into powder, and carrying out ball milling and sufficient mixing to prepare non-water-based ceramic slurry; (2) preparing ceramic mixed powder, namely drying, crushing and sieving the non-water-based ceramic slurry to form zirconium oxide mixed powder; (3) preparing a ceramic green body: pressing the zirconium oxide mixed powder into the ceramic green body through a press machine; and (4) carrying out pressureless sintering to obtain the zirconium oxide ceramic, and sintering and molding the ceramic green body in a tubular furnace under the protection of nitrogen. 本发明公开一种高熵稳定立方氧化锆和四方氧化锆相结构的方法，包括以下步骤：1)首先需要计算熵值并制备非水基陶瓷浆料
