Abstract AITranslate

Using TiO2,MoO3,Nb2O5,Ta2O5,ZrO2,B4C and carbon black as raw materials,(Ti,Mo,Nb,Ta,Zr)B2 high-entropy ceramic powder was prepared by high-energy ball milling and boro/carbothermal reduction method,with the phase composition and microstructure of the reaction products being characte-rized by XRD and SEM.The results show that ball milling time,reduction temperature,and holding time are important factors for the preparation of high-quality(Ti,Mo,Nb,Ta,Zr)B2 high-entropy ceramic powder.The high-quality(Ti,Mo,Nb,Ta,Zr)B2 high-entropy ceramic powder can be prepared with particle size of 1~2μm,uniform distribution of elements,and single phase composition under the conditions of ball milling time of 2 h,vacuum carbothermal reduction temperature of 1700℃,and holding time of 2 h.
