摘要: The structural change of carbon aerogels at high temperatures up to 2800°C has been investigated. Change in microtexture fine particles, which constitute derived from phenolic resin, was a typical non-graphitized carbon. microporosity decreased with an increase heat-treatment temperature, and disappeared 2000°C. mesoporosity still remained even after 2800°C, though 50% mesopore volume lost because the fusion particles microtexture.
