摘要： Silicon nitride based ceramic fibers containing Si, N, O and at least one metal M in amounts providing the atomic ratios N/Si of 0.3 to 3, O/Si of 0.0001 to 15 and M/Si of 0.001 to 5 and exhibiting an X-ray small angle scattering such that the ratio of the intensity of the small angle scattering of the fibers to that of air is 1 to 20. The ceramic fibers are produced by spinning of a polymetallosilazane into fibers and calcining the spun fibers and are useful as reinforcing fibers for composite artices having a metal or resin matrix.
