The highly reactive pentacoordinate silicon complexes from SiO2 were synthesized. By using functional halogen-containing compounds with reactive pentacoordinate silicon complexes, epoxide silicate substances were prepared. By controlling the hydrolysis of the epoxide silicate, a novel type of epoxy-functionalized silsesquioxane was yielded. And the synthesized product was characterized and analyzed by X-ray diffractometry, fourier transform infrared spectroscopy, and differential scanning calorimetry.

Key words: non-carbothermal method, epoxide silicate, silsesquioxane, silica
