Dense Reaction Infiltrated Silicon/Silicon Carbide Ceramics Derived from Wood based Composites

Wood‐based SiSiC ceramics with isotropic mechanical behavior were produced from commercial wood‐based composites (e.g., fiber boards). Properties can be tuned by the compression of the starting material, and by the content of added phenolic resin, which influences pore density and the amount of SiC infiltrated. In turn, the abundance of SiC versus residual silicon and carbon in the product determines its mechanical strength.
