Abstract
An article includes a ceramic-based substrate and a barrier layer on the ceramic-based substrate. The barrier layer includes a matrix of barium-magnesium alumino-silicate or SiO2, a dispersion of silicon oxycarbide particles in the matrix, and a dispersion of particles, of the other of barium-magnesium alumino-silicate or SiO2, in the matrix.
Claims7
A method of making a composite material comprising:
- mixing at least one of barium-magnesium alumino-silicate, SiO2, and colloidal silica with silicon oxycarbide in a carrier fluid to form a slurry;
- drying the slurry to remove the carrier fluid;
- and
- curing the slurry such that cross-linking occurs in the composite material.
