Development of a markedly excellent heat-resisting material may be possible by the combination of refractory metals and high-temperature ceramics. In this study joining between single-crystalline molybdenum and carbon-ceramics whose chemical composition and/or microstructure had been controlled was carried out by using precious metals (palladium, platinum) or active metal (zirconium). Fracture strength of the brazed joint was evaluated by the three-point bend tests at room temperature. Then the relation between the joint strength and the microstructure and/or chemical composition in and near the brazed layer was discussed.
