| 摘 要： | 制备ZnS超细粉通常是采用硫代乙酰胺(TAA)作为硫源，用化学合成法制取，但使用该原料在合成过程中易出现团聚现象，且价格昂贵；提出了采用一种低成本，且相对易于控制的原料硫代硫酸钠作为硫源，用均匀沉淀法制备ZnS超细粉的方法，并讨论了PH值温度对反应的影响。实验结果表明，用该方法可制得均匀、球形的ZnS超细粉末，且均匀粒径约为20nm。

| Abstract: | The common methods to prepare for ultrafine ZnS powder were chemically synthesized using thioacetamide (TAA) as the source of sulphur.But with this reagent,the powder is easy to conglomeration and the raw material is expensive.By using sodium thiosulfate as the source of sulphur,this paper submit a new method to prepare for ultrafine ZnS powder by homogeneous precipitation,and discuss the effect of pH and temperature on reaction.The experimetnal results show that this method can synthesize homogeneous and spherical ultrafine ZnS powder with the average size of 200nm. |
