N24-52 PROCESS FOR THE MANUFACTURE OF CERAMIC OXIDE FIBERS FROM SOLVENT SOLUTION Abstract of the Invention A process and apparatus for the manufacture of ceramic oxide fibers from solvent solution. The process comprises spinning a solution of a ceramic oxide precursor through openings having a diameter of from about 0.3 to about 1.5 millimeters, attenuating the resulting fibers with a stream of air to a diameter of less than 10 microns and heating the fibers in an oxygen atmosphere to form ceramic oxide fibers having a diameter of less than 5 microns. The apparatus com- prises a hollow rotatable disc having about 0.3 to about 1.5 millimeter holes in its circumferential edge; means for ro- tatably mounting the disc; means for introducing a solution of a ceramic oxide precursor into the disc; means for rotating the disc to force solution through the openings in fiber form; means for attenuating the fibers with a stream of air; and means for calcining the fibers.
