ABSTRACT:
The present invention provides a process for producing aluminum oxide fibers and, particularly, a process for producing aluminum fibers that have a high aspect ratio and can be accurately aligned, said process for producing aluminum oxide fibers comprising the steps of: uniformly mixing an aluminum or aluminum alloy powder with a boron oxide powder or a powder which, upon heating, can be converted to a boron oxide powder; and heating the mixed powder, or comprising the steps of: mixing not more than 50% by weight, in terms of titanium, of a titanium or titanium alloy powder to the starting mixture; and heating the mixed powder.
