TG-DTA and XRD were used to analyse the phase structure transformation of calcium-phosphate biomaterials fired and/or sintered at various temperatures,and animal tests were used to assess the biomechanical compatibility of the materials. The results demonstrate that proceeding parameters(pH value of sol-gel solution and firing or sintering temperature) exert a remarkable effect on phase transformation, and also that during a short time, biomechanical compatibility of β-TCP [Ca3 (PO4 )2] is superior to that of HA [Ca5 (PO4)6 (OH)2]; but with lasting implanting time, bio-mechanical compatibility of HA will surpass that of β-TCP.
