Patent ID: 7579424

Claim:
A ceramic made by a method comprising: providing a composition comprising: one or more compounds selected from siloxane linear polymer, metallic linear polymer, thermoset of a siloxane linear polymer, and thermoset of a metallic linear polymer, the compound comprising a backbone comprising: an acetylenic repeat unit; and one or more repeat units selected from —SiR 2 —(O—SiR 2 ) n — and —SiR 2 —(O—SiR 2 ) n -[Cb-SiR 2 —(O—SiR 2 ) n ] m —; wherein each R is an independently selected organic group; wherein each Cb is an independently selected carborane; and wherein each n is an independently selected integer greater than or equal to one; and wherein each m is an independently selected integer greater than or equal to zero; wherein any crosslinking comprises one or more of crosslinks between acetylene groups and polycarbosiloxane crosslinks; and one or more metallic components selected from: free metal atoms, metal clusters, or metal nanoparticles dispersed homogeneously throughout the composition; a (ML x ) y -acetylene complex in the backbone; and a metallic compound capable of reacting with the acetylenic repeat unit to form a (ML x ) y -acetylene complex; wherein each M is an independently selected metal; wherein each L is an independently selected ligand; and wherein x and y are positive integers; and pyrolyzing the composition.
