Abstract In present work, nano-carbon/ceramic composites are fabricated via facile reductive sintering of gel-casted bodies by utilizing different ceramic matrices of alumina and zirconia, respectively. With detailed characterizations of microstructure, bulk density and crystallinity of composites obtained at different sintering temperatures, as well as corresponding residual amount, chemical structure and bonding state of nano-carbon network, the influence of ceramic matrix on semi-conductive properties with respects to electrical conductivity, carrier density and mobility are systemically investigated. It is clarified that ceramic matrix plays an important role in tailoring the state of nano-carbon generated through ceramic particle surface and interface, which determines the resultant semi-conductive properties of composites.
