Abstract

Monomagnesium phosphate tetrahydrate (MMPT) has been synthesized and characterized by X-ray diffraction and thermal analyses techniques. MMPT is incongruently soluble and solids in equilibrium with a solution having an MG:P ratio of 1:2 coexist at an invariant point involving MMPT and MgHPO₄·3H₂O. MMPT exists in a P-tetragonal unit cell with room temperature lattice parameters: a = 13.712 Å and c = 21.984 Å. When MMPT is heated at atmospheric pressure MMPT initially transforms to the dihydrate. At higher temperature further transformations result in the simultaneous formation of the anhydrous phase and the pyrophosphate: MgH₂P₂O₇. With further dehydration, Mg(PO₃)₂ is formed.
