Sintering of TCP–TiO2 biocomposites: influence of secondary phases

TCP–TiO2 ceramic biocomposites with various α-to-β TCP ratios can be prepared by quenching the α phase. The presence of dopants (Ca, P, or Na) leads to the precipitation of secondary phases, which decreases the densification of titania. In the system TCP–TiO2, there is a eutectic with a composition of 63 wt% TCP–37 wt% TiO2 at a temperature of 1380°C.
