Abstract
A method of carbonizing cellulose-containing plants is disclosed. Wood is used as a precursor material which is carbonized under controlled temperature and atmosphere conditions to produce a porous carbon product having substantially the same cellular structure as the precursor wood. The porous carbonized wood may be used for various applications such as filters, or may be further processed to form carbon-polymer or carbon-carbon composites. The carbonized wood may also be converted to a ceramic such as silicon carbide. Additional processing may be used to form ceramic-metal or ceramic-ceramic composites.
Claims15
A porous ceramic-containing material comprising ceramic having a porous anisotropic cellular structure corresponding to a cellular structure of precursor wood.
A ceramic-metal composite article comprising:
- a ceramic having a porous anisotropic cellular structure corresponding to the anatomical structure of precursor wood;
- and
- metal at least partially filling the pores of the ceramic.
A ceramic-ceramic composite article comprising:
- a first ceramic having a porous anisotropic cellular structure corresponding to the anatomical structure of precursor wood;
- and
- a second ceramic at least partially filling the pores of the first ceramic.
