摘要:
A method for forming a polycrystalline ceramic fiber which comprises blending about 5 to about 25 weight percent polymer, about 70 to about 95 weight percent silicon carbide powder and greater than 1 weight percent sintering aid; forming a fiber from the blend; and sintering the formed fiber. Preferably, the sintering aid is boron carbide. In addition, the fiber is preferably pre-sintered at a first temperature of from about 1700.degree. C. to 2300.degree. C. and then subsequently sintered at a second temperature of approximately 2000.degree. C. to about 2300.degree. C.
