| Outline of Final Research Achievements |
To develop low-cost carbon nanotubes with high specific surface area and without catalytic metals, we investigated the synthetic condition of aligned and dense carbon nanotubes by the surface decomposition of SiC particles. First, it was revealed that the carbon nanotubes were synthesized in a simple and easy alumina tubular furnace. It was also confirmed that flowing adequate amount of oxygen gas into the furnace for some amounts of SiC particles and rotating the tubular carbon case supporting SiC samples to mixing them with an adequate rotation rate increased effectively the formation rate of the carbon nanotubes.
