Carbonate substituted hydroxyapatite (CHA) powder consolidated at 450°C

Carbonate substituted hydroxyapatite (CHA) powder consolidated at 450°C

CHA powder was consolidated without noticeable changing of its carbonate content using low-melting Na-Ca phosphate glass with the composition referred to 54% Na4CaP6O18 and 46% Na2CaP2O7 as a binder. A temperature window suitable for obtaining the composite was assessed as 450 – 475°C. The composite...

Zusammenfassung:CHA powder was consolidated without noticeable changing of its carbonate content using low-melting Na-Ca phosphate glass with the composition referred to 54% Na4CaP6O18 and 46% Na2CaP2O7 as a binder. A temperature window suitable for obtaining the composite was assessed as 450 – 475°C. The composites obtained at 450°C and 400 MPa for 1 hr demonstrate compressive strength up to 25 MPa.
