Preparation of porous Si-incorporated hydroxyapatite II 作者: Y.H. Kim, H. Song, D.H. Riu, S.R. Kim, H.J. Kim, J.H. Moon 出處: http://www.sciencedirect.com/science/journal/15671739/5/5

續前期

For the first step, natural 2 M (NH4)2HPO4 in the Teflon lined hydrothermal bomb and heated for 16 h at 180 °C. After the treatment of first step, X-ray powder diffraction of the sample shows a mixture of phases of aragonite, tricalcium phosphate and hydroxyapatite (Fig. 3a). As a second step, then block of mixed phases was transferred into silicon acetate saturated acetone solution and heated for 24 h at 180 °C in Teflon lined hydrothermal bomb.

After the treatment of second step, X-ray powder diffraction data of the sample still remains as a mixture of phases of aragonite, tricalcium phosphate and hydroxyapatite (Fig. 3b). Silicon concentration of the sample analyzed with EDS ranges from 0.12 wt% to 0.19 wt% and concentration at the surface is much higher than that in the interior.

When only hydrothermal treatment was applied to the natural coral in 2 M(NH4)2HPO4 in the presence of silicon acetate, EDS analysis shows only Ca, P, O and trace of Mg but silicon peak is not appeared. Normally, coral is known to contain trace amount of Mg ion since Mg content in seawater is quite high. However, the sample after repeated hydrothermal and solvothermal treatments contains small amount of silicon beside Ca, P, O, Mg and it is confirmed by EDS analysis (Fig. 4). For final step, block of coral was immersed in 2 M (NH4)2HPO4 and treated for 24 h at 200 °C hydrothermally again. After the treatment of final step, X-ray powder diffraction data of the sample confirmed that coral block converted mostly into hydroxyapatite phase (Fig. 3c).

The silicon-incorporated hydroxyapatite prepared from natural coral possesses uniformly permeable micropores and uniform pore volume measured by Archimedes method was about 70%. At the 70% porosity level, compressive strength of silicon-incorporated hydroxyapatite prepared from natural coral was 5.5 MPa. The prepared porous hydroxyapatite block is quite hard, which is not able to brake by pressing using a hand. At the same porosity, compared to compressive strength of 1.3 MPa of previously reported hydroxyapatite porous block which prepared using a polyurethane sponge technique, a substantial increase instrength has been obtained (Table 1).

Conclusions Both Ca and P ions in hydroxyapatite structure can be incorporated with various ions and isomorphous incorporation at each of this site is governed by ionic radii limits. Due to their ionic sizes, it is generally accepted that silicon substitutes for P site and exists as silicateion. To obtain porous hydroxyapatite block having an improved biocompatibility, Si-incorporated hydroxyapatite has been prepared using natural coral as a starting material. From the XRD, EDS analysis, they were confirmed that the single-phase hydroxyapatite with silicon level 0.19 wt% was synthesized. The Si-incorporated hydroxyapatite derived from natural coral exhibits a porous structure with all pores interconnected throughout the skeleton and structure resembles that of trabecular bone. Pore size distributions are ranged from 200μm to 300μm. Silicon incorporated porous hydroxyapatite material developed in the present study is expected to be a biomaterial having a good biocompatibility.
