磷酸锌制备

1.氧化锌法

将经稀释的15%磷酸溶液加入反应器中，在搅拌下缓慢加入浓度约20%的氧化锌浆液进行反应生成磷酸锌，温度保持在30℃以下，加入二水磷酸锌晶种，在Ph值为3的条件下加热至80℃，经过滤、热水洗涤、粉碎、于90℃下干燥，制得二水磷酸锌成品。其

2.复分解法

将磷酸三钠溶液加入反应器中，在搅拌下缓慢加入硫酸锌溶液，于70～80℃下进行复分解反应，完全反应后经过滤、用水漂洗除去硫酸根离子，再经粉碎、于120℃下干燥，制得二水磷酸锌成品。其
3.将硫酸锌和磷酸氢二钠(摩尔比为3∶2)的稀水溶液加热使之发生反应，即得四水合物的沉淀。此外，用稀磷酸溶液和氧化锌或碳酸锌反应，也可制得四水合物。于250℃加热失水得到无水磷酸锌。
