摘要: 在均匀沉淀法制备羟基锡酸锌的基础上,在反应体系中分别添加有机模板剂PEG400(聚乙二醇400)、PVA(聚乙烯醇),制得两种不同形貌的羟基锡酸锌晶体。通过X射线衍射(XRD)、扫描电镜(SEM)、热分析(TG),分别对产品的物相、结构、尺寸、形貌、热解行为进行了分析。研究结果表明,各产物都为立方晶系的羟基锡酸锌晶体,添加不同有机介质所得产品表面形貌各不相同。对有机介质改变羟基锡酸锌晶体形貌的影响机理进行了初步探讨。

Abstract: Based on the preparation of zinc hydroxystannate via homogeneous precipitation method,zinc hydroxystannates with two different morphologies were synthesized by added organic template PEG400 and PVA to the reaction system respectively.Phase,structure,size,morphology,and pyrolysis behavior of the products were characterized by SEM,XRD,and TG.Results showed that all the products were cubic ZnSn(OH)6 crystals and products had different morphologies by adding different organic media.Influencing mechanism of organic medium changing morphology of ZnSn(OH)6 crystals was also discussed preliminarily.
