摘要：

By using carboxy methyl chitosan (CMCS) and gelatin (Gel) as adhesive, the nano-HA slurry which was fabricated via a precipitation process as the raw material, dense HA spheres with a uniform size distribution and good geometry were prepared successfully by means of Sol-Gel method. Dense HA spheres with a porosity of 4.7%+/- 0.6% have a higher compressive strength (8.9 +/- 0.4) MPa than that of porous HA spheres (7.9 +/- 0.2) MPa with a porosity of 16.4%+/- 0.5% (particles with diameter of 0.5 mm). The results of biomimetic mineralization and cell culture show that dense HA spheres have an excellent biological property.
