The temperature dependence of the viscosity and stress-relaxation kinetics of sol-gel-derived SiOC glasses that contain up to 14 at.% carbon have been characterized in the temperature range of 1000-1400 deg C. The viscosity, as determined from relaxation experiments, is in good agreement with the creep viscosity and is typically two orders of magnitude higher than the viscosity of vitreous silica.
