heal.abstract	Over the last three decades the bioactive ceramics including bioglasses, glass-ceramics, sintered hydroxyapatite, become one of the major fields in biomaterials., due to their intimate bond with living bone through the formation of a biologically active carbonate apatite interface layer. The purpose of the work was to examine the structure of a calcium silicate bioactive glass prepared by the sol-gel method. The samples were characterized by thermogravimetric and differential thermal analysis (TG/DTA), Fourier transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD). No traces of organic matter or nitrates in the stabilized material were found according to FTIR and TG/DTA measurements. The materials produced are amorphous even after stabilization at 700 degrees C up to about 850 degrees C. However, the materials sinterized at 1000 degrees C for 1 hour reveal crystalline phase and indeed that of CaSiO3 (wollastonite). Thus, the materials prepared by the sol-gel method are homogeneous with high purity and after their stabilization below their crystallization temperature, they are amorphous. These characteristics allow their application in the area of orthopedic and dental implants as a bone substitute biomaterial.	en
