Resorbable Calcium Orthophosphates

State-of-the-art materials for resorbable calcium orthophosphate bioceramics as bone graft substitutes are still TCPs, either as the low temperature modification (0-TCP) or one of the high temperature modifications (a-TCP, a -TCP). The P-TCP is stable below 1125 °C. The a-TCP exists up to 1475 °C, and above this temperature up to the melting point at 1756 °C the a -TCP modification is stable (Figure 4.22).
