Abstract

For hydroxyapatite (HA) ceramics, sintering starts at 950-1000 °C through the formation of semi-hexagonal grains, and these grains coalesce to form quasi-hexagonal configurations between 1100 and 1200 °C. For tricalcium phosphate (TCP) ceramics, on the other hand, sintering starts at about 800 °C through the formation of a fibrous structure which coalesce to form grains at temperatures ranging from 1000 to 1200 °C. The difference in the starting temperatures for HA and TCP ceramics can be explained by the release of water of the latter. The decomposition of HA (with Ca/P to approximately 1.67) also partially inhibits the beginning of the sintering process.
