Abstract
Disclosed are novel monolithic ceramic bodies of the structure SiO.sub.y C.sub.z, wherein y=1.2 to 1.6 and z=0.2-0.6. These ceramic bodies are derived from a modified hydrogen silsesquioxane resin.
Claims11
A method of making a monolithic ceramic body comprising:
- forming a mixture comprising modified hydrogen silsesquioxane resin into a preceramic body;
- and
- heating the preceramic body to a temperature of at least about 1000.degree. C. in an inert atmosphere for a time sufficient to convert the preceramic body into a ceramic.
A monolithic ceramic body comprising silicon, carbon and oxygen having a stoichiometry of SiO.sub.y C.sub.z, wherein y=1.2 to 1.6 and z=0.21-0.6.
