Fabrication and Characterization of SiC-C Biomorphic Materials

Abstract:

Biomorphic SiO2/C and SiC/C composites containing SiO2 nanorods and SiC nanowires, respectively, with natural wood structure maintained in the final products were fabricated by a simple and low cost method. Freshly cut Luk bamboo was used as the starting material and was converted to charcoal bio-templates by pyrolysis. Infiltration of Si-containing metal-organic solution was then conducted by soaking the bio-templates into the solution for a few days. Finally, by high temperature annealing, biomorphic composites were produced. It was found that C, SiC, and SiO2 micron-sized spheres or nanorods, depending on the annealing duration, were present in the samples annealed at 1200°C; whereas only C, and SiC nanowires were present in the samples annealed at 1400°C.
