来自轻木和日本柏树的木材通过热解转化为碳质预制件，随后通过与 Na 和 Si 在 973 K 下加热 86.4 ks 转化为多孔 SiC 陶瓷。 X射线衍射表明所形成的SiC结构为立方β型。通过扫描电子显微镜观察到所得多孔 SiC 陶瓷的蜂窝结构与预成型体相似。
Wood from balsa and Japanese cypress was transformed into carbonaceous preforms by pyrolysis and subsequently converted into cellular SiC ceramics by heating with Na and Si at 973 K for 86.4 ks. X-ray diffraction showed the structure of the formed SiC to be cubic β-type. Cellular structures similar to those of the preforms were observed for the resulting porous SiC ceramics by scanning electron microscopy.
