摘要：
A crystalline ceramic fiber suitable for reinforcing a formed ceramic body is produced by crystallizing an amorphous ceramic fiber composed of silicon and nitrogen by heat treatment within non-oxide ceramic powder in an inert gas atmosphere. The amorphous ceramic fiber is produced by thermally decomposing a pre-ceramic fiber produced by melting and spinning polysilazane. The amorphous ceramic fiber is mainly composed of silicon, nitrogen, carbon, and oxygen, and has such a composition that silicon has a 40 to 60 weight %, nitrogen has a 5 to 40 weight %, carbon has a 20 weight % or lower, and oxygen has a 50 weight % or lower.
