Abstract
Attempts were made to prepare magnesium-containing calcium phosphate c ements. These were successful at the composition CaMg2(PO4)2xH2O. X-ra y diffraction showed that such a compound is not formed but that the c ement consists of magnesium phosphate precipitated on the calcium phos phate admixture. The pH of this formulation is around 10 during settin g and after. The cement is injectable. Its setting time is about 10 mi n. In this study compressive strength values were as high as 11 M Pa a nd the diametral tensile strength was over 2 M Pa. Animal experiments must show whether it is suitable for replacement or augmentation of bo ne in non-load bearing situations.
