制备

1.将3.4g ZnCl2溶于290mL水中制得的溶液加入至1L含有1mol磷酸和0.5mol吡啶的210mL吡啶磷酸溶液中，在水浴上加热4h，体系中的沉淀转化为晶体。

2.ZnSO4·7H2O 5.8g溶于100mL水所得溶液与2.5g Na2HPO4加热至沸腾搅拌，即得结晶四水磷酸锌沉淀。

3.将100g 69%的H3PO4溶液在沸腾情况下(121℃)与ZnO(约42g)发生中和反应，注意补充挥发的水。溶液冷却至室温，然后放置于冰浴中。剧烈搅拌下加入10倍体积的冰水，过滤，滤液滤入放于蒸汽浴上的瓷盘中，搅拌。过一会儿，透明的片状四水磷酸锌析出，抽滤，用沸水洗涤，干燥，得16g产品。

4.氧化锌法　将稀释的15%磷酸溶液加入反应器中，在搅拌下缓慢加入含量约20%的氧化锌浆液进行反应生成磷酸锌，保温在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，最后在120℃下干燥即得成品。反应式如下：

5.直接法　在盛有20%磷酸溶液的反应器中加入20%的氧化锌浆状溶液，在搅拌下调节pH值至2.0，加入晶种，调pH＝3，加热至80℃反应0.5h，过滤、洗涤分离，滤饼于120℃干燥得无水物。滤饼球磨得四水物。为了获得粒度微细、分散性好的产品，用表面活性剂首先对料浆进行改性，然后与磷酸在一定条件下反应制得。
