Graphite material and AlN ceramic were joined successfully using an interlayer tape of Ceramic Bonded Carbon (CBC) by spark plasma sintering. The CBC tape was prepared from the slurry of graphite and AlN powders by tape casting method. The CBC interlayer sintered consists of graphite particles bonded with the three-dimensional network of AlN thin layer. The graphite and AlN joints were analyzed by SEM observation, XRD phase identification, and EDX elements distribution. There were no cracks and voids at interfaces of AlN ceramic layer, CBC interlayer and graphite materials. It was suggested that the joining was performed mainly by sintering of AlN through the AlN ceramics layer and the CBC interlayer, and physical bonding between the CBC layer and graphite. The thickness of AlN layer and the CBC interlayer was about 3 % and 4 %, respectively, against the entire thickness of graphite and AlN joint. Nevertheless, the joints showed much higher strength of 82 MPa than the graphite's strength of 41 MPa. Graphite-AlN joints would be expected to use as light, insulative and high heat-conductive substrates or components.
