In This study synthesis of inorganic oxide material by a sol-gel technique through the formation of colloidal suspension (sol) and gelation of the sol into the gel enables incorporation of heat-sensitive active substances into the material during processing. Sol can be further processed into forms, such as monoliths(rod shape).The objectives of this study were to evaluate sol-gel derived silica gel as an implantable (monoliths). The structural properties of the prepared samples were studied, using X-ray diffraction (XRD) and Fourier transform infrared (FTIR), UV-VIS. Spectroscopy of xerogel silica and liner shrinkage of the samples.the sample prepared by mixing TEOS, ethonal, water, and HCL, TEOS and ethonal were mixing and stirred for 10 min at room temp.then 0.1 MHCL was gradually added to the solution until a water to TEOS molar ratio of R=2, R=5.The results shows that, silica xerogel has amorphous structure, FTIR spectroscopy has been used to find the amount of water (OH), it was found that when increase in temperatures the R (R=water: TEOS molar ratio) (R=2, R=5) the decrease intensity of H2O absorbance are consistent with loss of physisorbed wat
