Abstract

An object of the present invention is to provide a manufacturing method by which alumina-silica based fibers excellent in mechanical strength can be readily and securely obtained, and the present invention obtains precursor fibers as a material by using an alumina-silica based fiber spinning stock solution for use in an inorganic salt method. Next, the precursor fibers are heated under an environment which makes it difficult to carry out an oxidizing reaction on the carbon component contained in the precursor fibers. Thus, the precursor fibers are sintered to obtain alumina-silica based fibers.
