The invention belongs to the field of copper-based materials and preparation, and particularly relates to a rare earth copper material for a heat pipe and a preparation method of the rare earth copper material. Rare earth and cuprous oxide mixed powder is hydraulically formed and then added into copper liquid for refining. The rare earth oxide can be generated in situ in the copper liquid, particles are effectively prevented from agglomerating and growing due to the low diffusion rate, the particles are fine and high in dispersity, and the dispersion strengthening effect is further improved. In addition, by controlling the content of rare earth oxide particles, the fine, dispersed and low-content rare earth oxide can ensure that the influence on the electric conduction and heat conduction performance of the copper material is reduced to the minimum. When the rare earth copper material is used for processing a heat pipe shell, grain growth during sintering of the pipe shell can be effectively ...
