摘　　要：锡酸锌作为一种阻燃材料,已广泛应用于电缆、消防等相关领域。本文以氧化亚锡为原料,采用一步法合成锡酸锌的工艺进行了研究,对相关工艺参数进行了优化。通过实验得出最佳工艺条件为:反应温度为80℃,pH为8,双氧水浓度为25%,硫酸锌溶液浓度为20%,锡锌比为1:1.4,煅烧温度为250℃。该工艺路线为实现锡酸锌的工业化生产提供参考。Zinc stannate,as a flame retardant material,has been widely used in cable,fire protection and other related fields.In this paper,the one-step synthesis of zinc stannate from stannous oxide was studied,and the relevant process parameters were optimized.The optimum process conditions are as follows:The reaction temperature was 80℃,pH was 8,the concentration of hydrogen peroxide was 25%,the concentration of zinc sulfate solution was 20%,the ratio of tin to zinc was 1:1.4,and the calcination temperature was 250℃.The process provides a reference for the industrialized production of zinc stannate.
