Abstract: A wire catalyst for hydrogenation reaction and/or dehydrogenation reaction comprises a metallic core and an oxide surface layer covering at least part of the surface thereof. The metallic core is electrically conductive so that the metallic core itself can generate heat by directly passing an electric current therethrough or electromagnetic induction. The oxide surface layer is made of an oxide of a metallic element constituting the metallic core. The oxide surface layer is provided with a porous structure having pores opening at the surface of the oxide surface layer. The catalytic material is supported in the pores of the oxide surface layer. When a shaped wire catalyst is manufactured, the shaping into a specific shape is made before the oxide surface layer having the porous structure is formed and the catalytic material is supported thereon.

Abstract: PROBLEM TO BE SOLVED: To provide a wire tool that solves conventional wire tool problems and is suitable for machining a metal block of neodymium alloy that is hard and difficult-to-machine, by using a core wire having high strength and high elasticity irrespective of a fine wire, and superior twisting characteristics that suppresses fatigue breaking, and by using a CBN which is superior in thermal stability. SOLUTION: The wire tool is a wire tool for a wire saw and composed of the core wire and fine abrasives having an average grain diameter of 15-60 μm firmly adhered on an outer surface of the core wire via a metal coating layer, the core wire being an alloy-made, long length, and fine wire. The core wire has a tensile strength of 2,500-3,500 MPa and Young's modulus of 150-200 GPa. In the stress-strain diagram of the tensile test, the wire tool constituted of the alloy-made, long length fine wire of the high elastic type has the characteristics in which the actual area M 1 surrounded by the stress-strain diagram occupies, by area ratio, 80-98% of the right triangle M 0 which is drawn by connecting the datum line a, extension line b extending the proportional line of an elastic area, and a vertical line c passing the tension fracture point.
