Carbon tubules containing nanocrystalline SiC produced by the graphitization of sugar cane bagasse

Sugarcane bagasse was milled using a high-pressure (100 MPaG) homogenizer and then graphitized in the temperature range 1800-2400 °C. The samples obtained were examined by transmission electron microscopy. Carbon tubules containing nanocrystalline SiC were discovered. Their diameter and length were ca. 50-200 nm and 2-30 μm, respectively.
