Crystallization process improvement and fine-grained control, improved two ammonium and particle size of the crystals from the original non-reunion class reunion monocrystalline product changes, product processing, use, performance, adding seeds to eliminate the fine-grained control evaporation rate, the second crystal type and particle size ammonium achieve improved physical performance of products has reached the international advanced level. Seven ammonium production methods
