    Abstract: PROBLEM TO BE SOLVED: To obtain a corrosion resistant material which has not only a high corrosion resistance to halogen corrosive gases, such as fluorine corrosive gas and chlorine corrosive gas, and their plasma gases but has a good adhesion property to a base material, has no possibility of peeling and further has an excellent electrical conductivity and oxidation resistance as well. SOLUTION: The corrosion resistant material comprises the base material consisting of a sintered silicon carbide compact obtained by firing without being added with a sintering assistant and a diamond-containing carbon coating film covering at least a part of the base material and consisting of diamond single crystal particles, diamond polycrystalline particles, diamond-like carbon particles, or the like.

    Abstract: PROBLEM TO BE SOLVED: To provide a grounding resistor, which is free of fear of breakage, erosion, and local heat generation caused by thermal stress or a large surge voltage, whose impedance can be made small by stabilizing the impedance of the resister itself in a wide frequency band, and which has high mechanical strength and thereby is free of fear of the generation of failure, such as breakage, even when it is used at a place in a railway vehicle or the like, generating vibrations, and to provide a method of producing the same, by which the grounding resistors can be produced in a good yield with a high production efficiency. SOLUTION: The grounding resistor has a resistive element made of a silicon carbide sintered compact, and the silicon carbide sintered compact contains ≥10 wt.% silicon carbide crystal grains including aluminum in an amount of ≥0.04 wt.%.

    Abstract: PROBLEM TO BE SOLVED: To provide a high-frequency transmitting material which eliminates the possibility of the self-heat generation by high frequencies, does not give rise to a process defect, does not contain impurities to exert and adverse influence on an object to be treated, such as a wafer, is excellent in corrosion resistance and is free of toxici ty and a method of manufacturing the high-frequency transmitting material which can manufacture the high-frequency transmitting material having such characteristics. SOLUTION: The high-frequency transmitting material is formed to be composed of a silicon carbide-base sintered compact of =1×10 Ω.cm in volumetric resistivity value, and
