_{:In this paper, the exploration and research of W-Ce alloys were carried out to prepare high density and high calorific value active alloys. Porous W skeleton was prepared by isostatic pressing with W powder as raw material. Then the skeleton was sintered to improve the skeleton strength. Finally, W-Ce alloy material with high density W as skeleton and active Ce as filling phase was prepared by liquid phase infiltration of Ce. The microstructure, properties and reactivity of W-Ce alloys prepared by different W skeleton preparation processes were studied. The results show that the density of W-Ce alloys is above 95 %. The phase composition of the alloy is W and Ce, and no intermetallic compound is formed. The dynamic compressive strength ranges from 621 MPa to 905 MPa, and the dynamic compressive plasticity ranges from 20 % to 30 %. The W-Ce alloy has a lower reaction threshold.}
