氟硅酸钾制备
1.复分解法将氯化钾溶液（浓度约为22%～24%，过量20%～25%）于70～80℃和搅拌下加入氟硅酸溶液中，继续搅拌，然后静止20～30min，再经离心分离、用水洗涤、干燥、粉碎后，制得氟硅酸钾成品。其反应式如下：
将制得的氟硅酸钾溶液（10%～16%）在70～80℃下，用钾盐（氯化钾或硫酸钾）进行复分解（钾盐溶液浓度约为22%-24%，过量20%～25%）即得氟硅酸钾。其反应式如下。
氟硅酸与氯化钾的加料次序与生成的氟硅酸钾结晶大小有密切关系。在氟硅酸溶液中，在搅拌下加入钾盐能得较大晶体。加完钾盐后，继续搅拌，然后静置20～30min，使氟硅酸水解产物二氧化硅与氟硅酸钾分离，含二氧化硅的母液放置在沉降池中，可回收一部分氟硅酸钾。氟硅酸钾溶解度较小，故静置后即可离心分离，并用水冲洗至ph≥5为止。放入沉降池以回收氟硅酸钾。将晶体干燥、粉碎后即得成品。
