Recent Progress in Research on Woodceramics

Recent progress in research on a new kind of eco-material, woodceramics, is reviewed. Because of its unusual abrasive, sensitive and electromagnetic shielding properties, as well as unique structure, woodceramics will probably be widely applied as functional ceramics. The preparation methods, structure, performances, and preparing mechanisms of carbon woodceramics and SiC woodceramics are summarized. For an example of preparing β-SiC, the infiltration mechanism of Si into C preform and the corresponding infiltration-reaction models are presented. Besides the above-mentioned two kinds of woodceramics, other carbide woodceramics and oxide woodceramics are also introduced in brief. Finally, the existing problems and countermeasures of woodceramics are discussed and suggested, and their application prospects are proposed.
