Notes:
Ultra-high-temperature resistant Si-Al-C fibers derived from polyaluminocarbosilane wereprepared by the procedures of melt-spinning, air curing and heated at 1800°C. It was found that oxygencontent in the cured fibers has great influences on the chemical composition of the Si-Al-C fibers and itscrystalline behavior during sintering. When oxygen content of cured fibers was too high, crystallite grainsin the fiber would grow up. Oxygen evolvement in the fiber during the preparation was studied in detail bychemical analysis. It was found that oxygen is liberated mainly as CO gas from 1300°C to1600°C
