MAGNESIUM PHOSPHATE CAS 7757-87-1

What is MAGNESIUM PHOSPHATE?

Magnesium phosphate ( MAP) is an inorganic salt formed by the combination of magnesium ions with phosphate, hydrogen phosphate, or dihydrogen phosphate ions. It belongs to the magnesium salt family of phosphates and commonly exists as powder, granules, crystals, or amorphous solids.
