Preparation method of medium-entropy boron carbide ceramic

The invention relates to the technical field of carbide ceramics, in particular to a preparation method of medium-entropy boron carbide ceramics. According to the method, firstly, TiO2 powder, ZrO2 powder, Ta2O5 powder and C powder are subjected to ball milling and mixing and then subjected to two times of vacuum heat treatment to obtain (Ti1/3Zr1/3Ta1/3) C ceramic powder, then the (Ti1/3Zr1/3Ta1/3) C ceramic powder is mixed with B4C and then subjected to a boron heat reaction to prepare the medium-entropy (Ti1/3Zr1/3Ta1/3) ByCz boron carbide ceramic, and # imgabs0 is combined with the high-temperature-resistant characteristic of carbide and the anti-oxidation characteristic of boride, so that the medium-entropy (Ti1/3Zr1/3Ta1/3) ByCz boron carbide ceramic is prepared. The novel medium-entropy (Ti1/3Zr1/3Ta1/3) ByCz boron carbide ceramic with excellent performance is prepared, the operation is simple, rapid and controllable, the cost is low, and the green and energy-saving concept is met. 本发明涉及碳化物陶瓷技术领域，具体涉及一
