ZnS hollow microspheres with small open holes are successfully prepared by using heterogeneous-phase reflux technology.The paper explores the effect of the reaction conditions, such as refluxing time,stirring speed,reaction temperature,water-oil ratio and stirring method, on the morphology of ZnS microspheres.The suitable reaction conditions are obtained,that is, the water-oil ratio is 1∶4,the reaction temperature is 55 ℃,the stirring speed is 20 r/m,and the refluxing time is 2 hours.The obtained ZnS hollow microspheres have ideal form and well-dis-tributed size,and its average diameter of the microspheres is 8μm.
