Magnesium phosphate is a white crystalline salt composed of magnesium and phosphate ions, represented by the chemical formula Mg₃(PO₄)₂. It is widely used in medicine as a dietary supplement, in dentistry for bone regeneration cements, and in food processing as an anti-caking and pH control agent.
No. | Item | Specification | Result |

Food Grade:
1. Food Fortifier: Widely added to infant formula, foods for special medical purposes (STMP), high-calcium and high-magnesium dietary supplements, energy drinks, and pet food as a safe source of both magnesium and phosphorus.
2. Anti-caking Agent and Moisture Retention Agent: In powdered foods (such as milk powder, solid beverage powder, and compound flavoring powder), its microporous hygroscopic properties coat the powder surface to prevent moisture absorption and clumping, maintaining good flowability.
Daily Chemical Grade: Mild Abrasive in High-End Toothpaste: Used in high-end toothpastes. Its moderate crystal hardness effectively removes plaque and tartar from the tooth surface without physically scratching tooth enamel, while providing trace minerals to the teeth.
Industrial Grade:
1. Magnesium Phosphate Cement: A novel inorganic cementing material produced by the reaction of recalcined magnesia (magnesium oxide) with phosphates (including magnesium orthophosphate and its derivatives). This type of cement features ultra-fast hardening (curing within tens of minutes) and extremely high early strength, as well as low-temperature resistance, freeze-thaw resistance, and extremely strong bonding strength. It is widely used for emergency nighttime repairs of highways, bridges, and airport runways, as well as construction in high-altitude and cold regions and the solidification and sealing of nuclear waste.
2. Special Refractory Materials and High-Temperature Resistant Coatings: *Magnesium phosphate itself has an extremely high melting point and thermal stability. As a high-temperature binder in special ceramic binders and refractory castables, it can withstand temperatures of thousands of degrees Celsius without cracking or peeling.
Inner lining: polyethylene plastic bag; outer lining: woven plastic bag; each bag weighs 25 kg.
