Abstract

CO<SUB>3</SUB>apatites with different carbonate contents were synthesized at 60±1°C and pH 7.4±0.2 under different carbonate concentrations (0-0.3 mol/ L) in the supplied solutions. Their physicochemical properties were analyzed using various methods. Inductively coupled plasma gave accurate chemical analysis data for calcium and phosphate contents. X-ray diffraction analysis showed a clear chemical shift at high carbonate content. A CO<SUB>3</SUB><SUP>2-</SUP> absorption peak area approximately proportional to carbonate content was observed through Fourier transmission infrared spectroscopy. Scanning electron microscopy and high-resolution transmission electron microscopy revealed a dramatic change of the crystal shape. Osteoblast proliferation at the surface of each CO<SUB>3</SUB>apatite-collagen sponge indicated that osteoblasts deformed to expand and cover the surface of the sponge, and appeared to adhere well to the sponge.
