摘要
Biomorphic carbide ceramics MeC (with Me = Si, Ti, Zr) were produced by infiltration of low viscous organo-metallic colloidal suspensions into biologically derived carbon templates and hydrolyzed in situ to form hydrogels. After hydrolysis the infiltrated templates were submitted to a high temperature pyrolysis/reaction treatment at 1600degreesC to promote the decomposition of the gel into metal-oxides. A carbothermal reaction of the metal-oxides with the biocarbon template finally yielded biomorphous metal carbide ceramics.
