氟硅酸钠制备
2. 采用过磷酸钙副产法。将过磷酸钙（或萃取磷酸）生产过程中的含氟废气用水吸收，再与氯化钠反应而得。 3. 在试剂碳酸钠水溶液中，分次少量加入理论量的氟硅酸水溶液进行反应： 反应结束后，静置过滤，离心甩干，于120℃下干燥即可。 4. 过磷酸钙副产法 由磷矿粉和硫酸反应生产过磷酸钙或萃取磷酸时逸出的含氟废气，用水吸收四氟化硅使成氟硅酸。当氟硅酸溶液的含量达8%～10%时，静置澄清，除去杂质，澄清的氟硅酸溶液中加入氯化钠（过量约25%）反应，生成氟硅酸钠，经离心分离、洗涤、300℃以下温度下进行气流干燥，再经粉碎，制得氟硅酸钠成品。其反应式如下： 5. 将含二氧化硅4.6%和Na2SiH620.5%的氟硅酸用过量10%～20%化学计量的硫酸钠27%溶液处理，在硅酸溶胶中得到氟硅酸钠悬浮体。再在152～202.7kPa的压力下水力分离。副产物母液用干燥碳酸钠按8.8～9.3质量份/100质量份母液的比率中和副产母液，用86%～95%化学计量的硫酸钠处理氟硅酸，得到含78.5%～80.5%Na2SiH6的浆液。 6. 硫酸分解萤石矿生产氟硅酸钠的工艺流程如下：
