Hollow microfiber of ceramic material, process for the manufacture of hollow microfibers and use of hollow microfibers.

摘要

'' Hollow MICROFIBER OF CERAMIC MATERIAL, PROCESS FOR THE MANUFACTURE OF HOLY MICROFIBERS AND USE OF HOLY MICROFIBERS '', comprising hollow microfibers from ceramic material with a wall thickness of approximately 0.01 to 15 109 m external diameter of approximately 0.5 to 35 109 m. Hollow microfibers are produced, preferably, through a process, in which a dispersion containing the precursor of a ceramic material and a binder that can be removed under the effect of heat, is shaped in a peculiar way for new hollow microfibers, and the binder can eventually be removed under the effect of heat.
