Inorganic fibers including the following composition, SiO, AlO, MgO and CaO being main components, and the inorganic fibers being produced by a melting method: SiO: 3.0 wt % or more and less than 48.0 wt %, AlO: more than 20.0 wt % and 80.0 wt % or less, MgO: 1.0 wt % or more and 50.0 wt % or less, CaO: 1.0 wt % or more and 50.0 wt % or less, and FeO: 0.0 wt % or more and less than 1.0 wt %.

Biosoluble inorganic fiber

Disclosed herein is a bio-soluble inorganic fiber with high tensile strength, manufactured in a method comprising: heating and melting a raw material which includes, on a weight basis, 60 to 80 percent of SiO, 5 to 20 percent of MgO, 5 to 30 percent of CaO, 0.5 to 5 of AlO, and 0.1 to 5 of BaO, at a temperature of 1800 to 2100 degrees Celsius; and exposing the melting material to an air flow for fiber forming.

Inorganic fiber and method for manufacturing the same

A holding material used for a catalytic converter having a catalyst carrier shaped like a cylinder, a casing for receiving the catalyst carrier, and the holding material mounted on the catalyst carrier and interposed in a gap between the catalyst carrier and the casing, the holding material including a molding of inorganic fibers shaped like a mat or a cylinder, wherein at least an exhaust-gas-inlet-side end portion of the holding material is set to be smaller in basis weight than any other area of the holding material over a predetermined axial length.
