摘要：

Processes for producing the monohydrate form of magnesium ammonium phosphate in slurry from use of environmentally friendly reactants are described. Slurry containing the monohydrate form of magnesium ammonium phosphate can be fed directly to, and mixed with, paper making feedstock, such as feedstock for cigarette paper, without transformation of the monohydrate form to the hexahydrate form of magnesium ammonium phosphate.
