Bone cements of calcium-magnesium phosphate and magnesium oxide

The new bone cements were obtained in the calcium phosphate – magnesium phosphate system. The cement powders were synthesized by precipitation method and calcium-magnesium phosphates and magnesium oxide were obtained. The cement liquids based on Na2HPO4 and NaH2PO4 characterized by pH 3.5-5.5 were used and cements phase composition, microstructure, and mechanical properties depending on pH of cement liquid were investigated. Due to the ability to form high-strength cement stone with compressive strength up to 40 MPa and setting time 10-12 minutes, these materials are promising candidates for use as the bone cements.
