Abstract

A systematic study of the stability of potassium/carbonate co-substituted hydroxyapatite has been carried out, with samples synthesized by aqueous precipitation according to the charge-balanced mechanism:

Ca10-xKx(PO4)(6-x)(CO3)(x)(OH)(2)

Samples up to x=1.0 were prepared and their stability determined by heating at a range of temperatures in both air and CO2 environments. Results showed that whilst samples up to x=1.0 can be prepared phase-pure, the stability of these materials is strongly dependent on sintering temperature with the full range of compositions only being stable at 600 degrees C in CO2. The c unit cell parameter increases linearly with x, and, for a fixed composition, decreases linearly with temperature indicating loss of carbonate from the A-site. FTIR showed that samples contained carbonate at both A- and B-sites, and that carbonate content increased with x.
