Abstract:
A method of making ceramic fibers from a water soluble pre-ceramic polymer solution by forming fibers from a water soluble pre-ceramic polymer solution, drying the formed fibers at a first temperature ranging between 600. degree. C. -750. degree. C. at a temperature heating rate of about 1. degree. C. per minute. Next, raising the first temperature to a second temperature ranging from 800. degree. C. -1000. degree. C. at about 5. degree. C. per minute, and increasing the second temperature to still a third temperature of about 1200. degree. C. at about 10. degree. C. per minute and holding at the third temperature for about 1 hour. Finally, the fibers are cooled to room temperature at a rate of about 5. degree. C. to 30. degree. C. per minute.
