Magnesium Phosphate Cement Formula

  • Magnesium Phosphate Cement

    Addition of soluble phosphates to Sorel (magnesium oxychloride) cement improves water resistance by the formation of insoluble complex This gives rise to aluminium phosphates with a Al 2 O 3 /H 3 PO 4 molecular ratio of 11 or 14, or to the calcium phosphate hydrates Ca 5 (PO 4) 3 OH or CaH 2 PO 4 H 2 O The phosphate appears to be adsorbed onto the surface of the hydrating grains.
