실험 절차

Thus, the overall process for producing the present inventive magnesium ammonium phosphate monohydrate slurry may be summarized as follows: (a) obtaining a magnesium hydroxide slurry having magnesium hydroxide particles wherein at least about 55 wt. % of the particles have a size less than about 2 microns; (b) then adding ammonia; (c) while maintaining an excess of ammonia and cooling, adding phosphoric acid at a rate so as not to exceed a temperature of about 110° F.; (d) producing a magnesium ammonium phosphate hexahydrate slurry; (e) heating the magnesium ammonium phosphate hexahydrate slurry to its boiling point.
