Production method

●  Fluoroboric acid ammonia neutralization method Hydrofluoric acid and boric acid are fluorinated in a fluorination kettle at below 60 ° C for more than 2 hours to obtain a fluoroboric acid solution, which is sent to the ammoniation kettle, neutralized by ammonia gas, and controlled by a flow meter. quantity. A large amount of heat was generated during the reaction, and an ice bath was set outside the kettle for cooling. Always measure the ammoniation temperature and adjust the ventilation rate. When the pH reaches 3 to 4, stop the ammonia flow. After cooling and cooling, the product that has been crystallized is separated, the residual liquid is evaporated and concentrated, crystallized by cooling, centrifuged, and dried at below 80° C. to obtain the finished product of ammonium fluoroborate. That
HBF4+NH3→NH4BF4
