    摘要: Provided is a sintered object which has excellent resistance to corrosion by corrosive halogen gases and by the plasmas thereof and has excellent thermal conductivity and excellent electrical conductivity. Even when applied to members for use in various vacuum process devices, the sintered object has few limitations on design. The sintered object is usable in a wide range of applications, and is highly versatile. Also provided is a method for producing the sintered object. Furthermore provided is a high-frequency transmission material which has direct-current electrical conductivity for reducing fluctuations in plasma potential and has capacitive properties that enable the material to transmit high-frequency power necessary for plasma excitation, and which has no fear of causing contamination of a sample with a metal and has resistance to corrosion by plasmas. Still further provided are: a sintered object which has excellent resistance to corrosion by corrosive halogen gases and by the plasmas thereof and has no frequency dependence when a high-frequency voltage is applied thereto and with which it is possible to actualize the stability of a plasma; and a method for producing the sintered object.

    摘要: Composite structures of carbon nanotubes (CNTs) and metal carbides include a helical nanotube/carbide composite fiber, and a film. The composite fiber was prepared by pulling/twisting carbon nanotubes from an array of nanotubes to form an as-spun fiber and soaking it a metal precursor solution, and then heating it under a reducing atmosphere with a carbon source. The composite fiber had a higher tensile strength, a higher conductivity, and a higher tensile modulus than the as-spun fiber. A composite structure in the form of parallel ribbons of aligned carbon nanotubes embedded in a film of NbC showed an enhanced conductivity along the CNT axial direction, and improved superconducting properties. The enhanced upper critical field of NbC/CNT suggested that the inclusion of CNTs in the NbC matrix reduced the coherence length of the NbC. Nanomechanical testing also demonstrated the potential for enhanced fracture toughness of NbC/CNT composites.
