Calcium phosphate based ceramic with a resorbable phase and low sintering temperature

The use of glasses with eutectic compositions in the system CaO-P2O5 as a sintering aid and as a source of a resorbable phase for obtaining a composite biomaterial for bone implants is examined. The use of such glass has made it possible not only to lower the sintering temperature by realization of the mechanism of liquid-phase sintering but also to form a ceramic material possessing bioresorbability. The material obtained consists of calcium hydroxyapatite, vitlokite, and calcium pyrophosphate phases.
