    • An organosilicon high molecular compound having a skeleton of silicon and carbon or a compound obtained by polymerization of an organometallic compound and the organosilicon high molecular compound is melted into a fiber, then the fiber is antimelt-treated in an oxidizing atmosphere, and the antimelt-treated yarns are thereafter heated in an atmosphere of inert gas to obtain a fiber of silicon carbide containing 2 to 20% by volume of oxygen. This fiber is further sintered in an atmosphere of inert gas at a temperature of 1400 to 2100 deg. C. and a pressure of 300 to 3000 kg/cm.sup.2. A sintered body of silicon carbide having an excellent bending strength is obtained without the use of a sintering agent or a binder. A fiber of silicon carbide having a predetermined oxygen content and a thin amorphous carbon layer thereon is obtained from the starting fiber by antimelt-treating and then heating in an atmosphere of a mixture of an inert gas and a hydrocarbon gas. Silicon carbide powder is mixed with the fiber thus obtained and the mixture is then heated in an atmosphere of inert gas under pressure. The sintered body thus obtained has a high strength and a remarkably small decrease in strength at high temperature.
    • 将具有硅和碳骨架的有机硅高分子化合物或通过有机金属化合物和有机硅高分子化合物的聚合得到的化合物熔融成纤维,然后将纤维在氧化气氛中进行电镀处理, 然后在惰性气体气氛中加热处理后的纱线,得到含有2〜20体积%氧气的碳化硅纤维。 该纤维在1400〜2100℃的惰性气氛中进一步烧结。 并且压力为300至3000kg / cm2。 在不使用烧结剂或粘合剂的情况下,获得具有优异弯曲强度的碳化硅烧结体。 通过抗熔融处理从起始纤维获得具有预定氧含量的碳化硅纤维和其上的薄无定形碳层,然后在惰性气体和烃气体的混合气氛中加热。 将碳化硅粉末与由此获得的纤维混合,然后将混合物在惰性气体气氛中加压。 这样得到的烧结体的强度高,在高温下的强度明显降低。
