Fabrication of Carbonate Apatite Based on Hydrothermal Reaction Using Freeze-Casted β-TCP Precursor

Abstract:

Carbonate apatite (CO₃Ap) has similarity to biological bone in composition which is expected to induce excellent tissue response and osteoconductivity. CO₃Ap with lower crystallinity also promotes more apatite absorption in vivo. This study aims to fabricate low crystallinity of carbonate apatite from β-TCP scaffold as precursor using hydrothermal treatment at 200oC. An interconnected structure of β-TCP scaffolds were fabricated by freeze casting method which immersed in 5 mol/L of disodium carbonate (Na₂CO₃) solution for hydrothermal with various days of treatment; 3, 5 and 7 days. The morphology of apatite transformed was investigated by scanning electron microscopy (SEM) while the crystallinity was measured by X-ray diffraction (XRD). The carbonate content and Ca/P ratio after hydrothermal were obtained by CHN analyzer and X-ray fluorescence (XRF), respectively. The results show that carbonate content higher than 11 wt% was obtained which is important for both cell adhesion and proliferation. The apatite structure in the form of needle-like crystal is also observed.
