    • Abstract


      Ceramic carbon composites were fabricated by colloidal processing using glucose as soluble carbon source.Glucose is converted into conducting carbon at high temperature treatment. Ceramic carbon composites were sintered inflowing argon at 1400◦C showing resistor behaviour even at low carbon content (1 wt%). In this work, ceramic carboncomposites were fabricated using alumina–clay slurries with addition of glucose as a soluble carbon source. Morphology ofthe sintered samples was characterized by field emission gun (FEG) electron microscopy. Phase analysis was done by X-raydiffraction (XRD). Electrical properties of ceramic carbon composites were measured by broad band dielectric spectrometer.Carbon produced from glucose at high temperature was characterized independently by BET surface area, dynamic lightscattering, field emission gun scanning electron microscopy, field emission gun transmission electron microscopy, XRD andRaman spectroscopy.
