Abstract
Trimagnesium phosphate hydrate was synthesized by mechanochemical reaction of a slurry of magnesium hydrogen phosphate trihydrate and magnesium oxide with the molar ratio of 2:1 in a pot mill for a few hours. Mg3(PO4)2⋅8H2O was obtained by using a slurry with more than 60wt% water; Mg3(PO4)2⋅22H2O, with 40wt% water. The anhydrate of trimagnesium phosphate was obtained by heating Mg3(PO4)2⋅8H2O or Mg3(PO4)2⋅22H2O above 700°C.
