Method for preparing compact (HfZrTaNbTi) C high-entropy ceramic sintered body through normal-pressure sintering
The invention relates to a method for preparing a compact (HfZrTaNbTi) C high-entropy ceramic sintered body by normal-pressure sintering, which comprises the following steps: (1) selecting HfC powder,ZrC powder, TaC powder, NbC powder and TiC powder as raw materials, adding an adhesive and a solvent, and performing mixing to obtain slurry; (2) drying, sieving or spray-granulating the obtained slurry to obtain mixed powder; and (3) carrying out compression molding and vacuum debonding on the obtained mixed powder, then placing the mixed powder in an inert atmosphere, and carrying out normal-pressure sintering at 2000-2250 DEG C to obtain the high-entropy ceramic sintered body.
本发明涉及一种常压烧结制备致密(HfZrTaNbTi)C高熵陶瓷烧结体的方法，包括：（1）选HfC粉体、ZrC粉体、TaC粉体、NbC粉体和TiC粉体作为原料，再加入粘结剂和溶剂混合，得到浆料；（2）将所得浆料干燥过筛或喷雾造粒，得到混合粉体；（3）将所得混合粉体经压制成型和真空脱粘后置于惰性气氛中，在2000～2250℃下常压烧结，得到所述高熵陶瓷烧结体。
