| Abstract: | According to nature of the fluxing agents,ammonium sulfate was chosen as better fluxing agent with sodium hexametaphosphate and sodium fluoride used for the major reacting materials.The influences of drying temperature,drying time,synthesis temperature,synthesis time,[（F）/（P）] and n [（NH 4） 2SO 4] ∶ n [（NaPO 3） 6＋NaF] on the synthesis of sodium monofluorophosphate were investigated by single factor experiment.The optimal process conditions were confirmed by selective preference of orthogonal test. |
| Keywords: | Sodium monofluorophosphate Ammonium sulfate Fluxing agent |
