<p>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 comprises a rotatably mounted hollow disc (12) having about 0.3 to about 1.5 millimeter holes (24) in its circumferential edge (22). Means (28 30) are provided for introducing a solution of a ceramic oxide precursor into the disc (12) which may be rotated by means (36. 38. 40. 42) to force solution through the openings (24) in fiber form. Means (44. 46) provide an air stream (51) for attenuating the fibers, and means are also provided for calcining the fibers.</p> |
