| Abstract: | Monolithic silica glass was obtained by heating the gels preparedby hydrolyzing Si(OC_2H_5)_4 with HCl solution.The effect of the condition ofhydrolysis of Si(OC_2H_5)_4 on glass formation was examined by measuring thebulk density,the infrared spectra,DTA and TGA of the gel on heating. |
