Process for producing alumina fiber or alumina-silica fiber |
摘要 |
A process for producing alumina fiber or alumina-silica fiber having excellent mechanical strength and heat resistance, comprising (i) spinning a solution of at least one polyaluminoxane or of a mixture of at least one polyaluminoxane and one or more kinds of silicon-containing compounds in an organic solvent, (ii) hydrolyzing the resulting precursor fiber, and then (iii) calcining the hydrolyzed fiber, said polyaluminoxane being one or more kinds of polymers or copolymers which mainly consist of the structural units of the formula: <IMAGE> wherein the pendant groups Y are one or more kinds of groups selected from the group consisting of an alkyl, an alkoxy, an acyloxy, phenyl and phenoxy, and which may be partially a halogen or hydroxy.
