Description
Magnesium phosphate occurs in three forms: monobasic, dibasic, and tribasic. Dibasic and tribasic magnesium phosphate are the most common. They are used as antacids, food additives, polishing agents, and as stabilizers in plastics. Monobasic magnesium phosphate is one type of magnesia cement, magnesium phosphate cement (MAP). It is formed by the reaction between magnesium oxide and a soluble phosphate, such as ammonium phosphate monobasic (NH4H2PO4). MAP sets rapidly with very high early strength. It is known for good adhesion as well as good water and freeze thaw resistance.
