High temperature materials can be manufactured cost effectively using high yield, thermally stable, silicon carbide (SiC) or silicon oxycarbide (SiOC) forming polymers. A number of SiC forming polymers are commercially available products, while the SiOC precursors are currently available to commercialized .

Both types of precursors are low viscosity liquids, with low surface tensions, that provide for excellent wetting of fibers, powders and preforms. They typically cure with a platinum or peroxide catalyst at temperatures below 200°C. These polymer types are soluble in solvents such as hexane, tetrahydrofuran, toluene, xylene and acetone. Both classes of XBH polymers have high ceramic yield when processed under inert gas to 800°C to 1400°C. The SiOC precursors can be cured in air but the SiC precursors should be cured in an inert environment.
