  • Method of producing inorganic oxide fibers with axially aligned porosity
    Patent number: 5176857
    Abstract: A porous low density inorganic oxide fibre of improved strength and flexibility has at least 25% of the porosity provided by axially aligned pores. The fibres are produced by spinning into fibres a spinning solution in which is incorporated a non-ionic surface active agent having a cloud point in the solution above the fibre spinning temperature and less than 20.degree. C. above the fibre spinning temperature, preferably within the range of 5.degree.-15.degree. C. above the fibre spinning temperature. The fibre may be an alumina fibre which can be free from silica and is useful as reinforcement in MMCs.
