Summary

Carbon-containing monolithic glasses were prepared by the inert atmospheric pyrolysis of glass precursors (dry gels) made from methyltrimethoxysilane and colloidal silica via the sol-gel process. These glasses have mechanical and thermal properties comparable to those of fused quartz but with lower volume resistivity and a low tendency toward devitrification. Characterization of a glass made from MeSiO3-SiO2 (55:45 by weight) indicated that the glass has an empirical formula of SiO1.7C0.2- The bulk density, porosity, and pore size of the glass are 1.8 g/cm3, 20%, and <5000 nm, respectively.
