High temperature preparation of silicon containing apatite

Several studies have shown that silicon presence is beneficial in bone mineralization process. Phosphocalcium hydroxyapatite (HA: Ca10(PO4)6(OH)2) is the principal mineral component of bone. This work studies the synthesis of silicon containing apatite by a high temperature method. The stable compound at high temperature seems to be the silicocarnotite. Nevertheless, a silicon containing apatite has been obtained by heating a mixture of tri-calcium phosphate, calcium carbonate and silicon dioxide at 1200°C-1300°C. The synthesized materials can be used in medicine as bone substitution or as proŃsthesis and implant coating.
