What is the highest nitrogen content of slurry ammonium phosphate? Thank you for your questions.

The nitrogen content of ammonium phosphate produced by slurry method is less than 16%~ 18%. Because of the high impurity content in dilute acid, the nitrogen content produced by traditional method can reach more than 17.5%. Because most impurities and phosphogypsum are precipitated in the process of phosphoric acid concentration, the nitrogen content of ammonium phosphate produced by traditional method is higher than that by slurry method.
