With a magnesium salt stabilized hydraulic brushite cement

摘要

The brushite cement for surgical purposes comprises a first component comprising a basic calcium phosphate, a second component comprising an acidic phosphate, a third component comprising water, and a fourth component comprising a source of magnesium used to stabilize the end-product of the setting reaction between the components. The solubility of the source of magnesium is smaller than 100 g/L. The components are chosen in such an amount that (i) the pH of the cement paste during setting is lower than 6,0; and (ii) the end-product of the setting reaction comprises dicalcium phosphate dihydrate [CaHPO4.2H2O].
