Abstract:

Bone-like nanograde hydroxyapatite(HAP)spicula were synthesized in simulated body fluid(SBF)by increasing the concentration of Ca and P in the SBF by a biomimetic method. The mass phase composition, chemical composition, micromorphology, thermal stability, bioactivity and high temperature during stability at different sintering temperature 500～1300℃ of the obtained HAP were studied by X-ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscope, differential thermal analysis and atomic absorption spectrometry. The results indicated that the synthesized HAP had a pin-like shape close to natural bone with a 70～80nm length and 10～20nm width. Though the degree of crystallization of HAP is better and better with temperature increasing, the HAP could be decomposed when the sintering temperature is above 1000℃.The synthesized HAP powders have good ability for inducing the deposition of Ca and P.

Key words: simulated body fluid, hydroxyapatite, biomimetic synthesis, high temperature stability
