The Nb₃Sn was successfully prepared by a fast and convenient method in which the mixture of the Nb, Sn, and Cu powder was mechanically alloyed followed by heat treatment. The morphology, crystal structure, and critical temperature were measured by SEM, XRD, and VSM. The results show that with increased milling time, the size of the powders becomes increasingly homogeneous and uniform. The addition of copper to the blended powder makes it easier to form the final Nb₃Sn. With the increase of milling time, the particle size and crystallite size decreased, and the tin diffraction peaks disappeared when the milling time was more than 3 h. The effect of surfactants on the process of milling was studied. The phenomenon of adhering to the wall was relieved when even a small amount of stearic acid was introduced into the reactants. After the process of milling, the time needed for heat treatment was greatly reduced; it only needed a few hours at the maximum temperature stage. The critical temperature of the products is over 17 K after a heat treatment of only 1 h, which greatly reduces the time and cost of the heat treatment process, indicating that the as-prepared products have potential applications for preparing Nb₃Sn superconducting materials.

Nb ₃ Sn 是通过快速方便的方法成功制备的，其中 Nb、Sn 和 Cu 粉末的混合物进行机械合金化，然后进行热处理。通过SEM、XRD和VSM测量了形貌、晶体结构和临界温度。结果表明，随着研磨时间的增加，粉末的尺寸变得越来越均匀和均匀。在混合粉末中加入铜可以更容易地形成最终的 Nb ₃锡。随着球磨时间的增加，粒径和晶粒尺寸减小，球磨时间超过3 h时锡衍射峰消失。研究了表面活性剂对研磨过程的影响。即使在反应物中加入少量的硬脂酸，粘壁现象也会得到缓解。铣削加工后，热处理所需时间大大减少；在最高温度阶段只需要几个小时。仅经过1 h的热处理，产物的临界温度就超过了17 K，大大降低了热处理过程的时间和成本，表明所制备的产物在制备Nb ₃ Sn超导材料方面具有潜在的应用价值。
