ALUMINA-SILICA-BASED FIBER, METHOD FOR PRODUCING THE SAME, AND MAINTAINING SEALANT FOR CATALYST CONVERTER

摘要

PROBLEM TO BE SOLVED: To provide a method capable of simply and certainly producing an alumina-silica-based fiber excellent in mechanical strengths. SOLUTION: A precursor fiber is produced by using an alumina-silica-based fiber dope for the inorganic salt method as a source material. Subsequently, the precursor fiber is heated under a condition in which the oxidation reaction of carbon component included in the precursor fiber is reduced. Thus, a alumina- silica-based fiber 6 is obtained by baking the precursor fiber.
