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.
