摘　　要：采用超声法制备了镓铟锡合金(Galinstan)液态金属微球,研究了超声工艺参数对Galinstan微球粒径的影响规律,然后通过控制沉降时间进行多次沉降,得到了均匀分布的亚微米级Galinstan微球。结果表明:Galinstan微球粒径随着超声时间、功率的增加而减小,随着超声温度、溶剂表面张力的增加而增大,通过优化超声工艺参数,可以获得粒径小于2μm的Galinstan微球;经过多次沉降去除沉降的大粒径微球,可以获得粒径分布范围为0.2~0.8μm的Galinstan微球,大大提高了微球粒径分布均匀性。Gallium-indium-tin alloy（Galinstan） liquid metal microspheres were prepared by ultrasonic method,and the effects of ultrasonic process parameters on the diameter of Galinstan microspheres were studied. Then,the uniformly distributed sub-microsized Galinstan microspheres were obtained by controlling the settling time. The results show that the diameter of Galinstan microspheres decreased with the increase of ultrasonic time and power,and increased with the increase of ultrasonic temperature and solvent surface tension. By optimizing the ultrasonic process parameters,Galinstan microspheres with the diameter less than 2 μm could be obtained. Galinstan microspheres with a diameter range of 0.2-0.8 μm could be obtained by multiple sedimentation to remove the large-size microspheres. This method could greatly improve the homogeneity of particle diameter distribution of the microspheres.
