摘要
用溶胶-凝胶法将Si(OC_2H_5)_4在催化剂的作用下水解聚合成凝胶。测定了凝胶的粘度变化、热重分析、差热分析、松密度和红外吸收光谱。并对不同条件下溶液的胶凝时间做了测定,探讨了水解-聚合-干凝胶-石英玻璃的转变过程.
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.
