Method for modifying boride ceramic powder with Mo
The invention relates to a method for modifying boride ceramic powder by Mo, which comprises the following steps of: uniformly mixing boride ceramic powder (HfB2, ZrB2, NbB2, TaB2 and TiB2) and Mo-containing compounds (MoO2, MoO3, Na2MoO4, H2MoO4, (NH4) 6. Mo7O24, (NH4) 2. Mo4O13 and (NH4) 2. Mo2O7) serving as raw materials, and performing heat treatment in a protective atmosphere and a reducing atmosphere, so that Mo particles are coated on the surfaces of the ceramic powder particles, and the ceramic powder is prevented from being oxidized and impurity phases are prevented from being generated. The method can realize modification of Mo on the surface of the boride powder, so that the refractory metal Mo and the ceramic powder are uniformly mixed, and powder agglomeration is avoided.
一种Mo修饰硼化物陶瓷粉体的方法，该方法采用硼化物陶瓷粉体（HfB2、ZrB2、NbB2、TaB2、TiB2）和含Mo的化合物（MoO2、MoO3、Na2MoO4、H2MoO4、(NH4)6·Mo7O24、(NH4)2·Mo4O13、(NH4)2·Mo2O7）为原料，将其混合均匀后在保护气氛和还原气氛中完成热处理，实现Mo颗粒在陶瓷粉体颗粒表面的包覆，并避免陶瓷粉体氧化及产生杂质相。该方法可以实现Mo在硼化物粉体表面的修饰，使难熔金属Mo与陶瓷粉体均匀混合并避免粉体团聚。
