Summary

Highly porous, cellular SiC–ceramics with a unidirected pore structure were manufactured by infiltration of pyrolysed hardwood (Pine), softwood (Oak) and Rattan at 1600°C in inert atmosphere with two different gaseous precursors: Si and SiO–vapors. Pyrolysis of the natural wood, infiltration and reaction into SiC was monitored by scanning electron microscopy (SEM), X–ray analysis (XRD) and fhermogravimetry analysis (TGA/DTA). Depending on the kind of wood as well as on the infiltration and reaction parameters, grain size and specific surface area can be tailored in a broad range. The compressive strength parallel and perpendicular to the cell elongated direction of the porous SiC–ceramics were characterized.
