摘要：
The aim of this work was synthesis and characterization of amorphous and crystallized 58S nanopowders produced via sol-gel method. According to the thermal analysis, the nanopowders were heat-treated at 600 degrees C and 1100 degrees C. X-ray diffraction results revealed that the phases of Wollastonite and tricalcium phosphate were formed at 1100 degrees C. The in vitro tests showed that hydroxyl carbonate apatite was precipitated on both crystallized and amorphous nanopowders, while amorphous nanopowder showed a higher bioactivity than that of crystallized nanopowder. In contrast, mechanical properties of crystallized specimen were higher than those of amorphous specimen.
