Process for preparing oxynitride ceramic fibers |
摘要 |
The process of this invention for preparing oxynitride ceramic fibers comprises spinning a viscous sol obtained by the hydrolysis of a feed mainly consisting of metal alkoxides, steam-treating the gel fibers, and firing the steam-treated gel fibers in a stream of ammonia and is commercially useful for the production of oxynitride fibers with excellent hardness, strength, modulus of elasticity, heat resistance, and corrosion resistance.
