ABSTRACT:
Disclosed is a liquid, boron-containing, inorganic oxide resin containing unsaturated organic groups. The resin can additionally comprise the units .brket open-st.M-O.brket close-st., where M can vary from one unit to the next and is selected from Si, Ti, Al, Ba, Zr, Li and Hf. Also disclosed is a process for inhibiting the oxidation of carbon-carbon composites by impregnating the composite with such resins, cross-linking the resin and pyrolyzing to convert the resin to a ceramic material.
