| titleOfInvention | Continuous inorganic fibers and process for production thereof |
| abstract | ABSTRACT OF THE DISCLOSURE Continuous inorganic fibers consisting substantially of Si, Zr and C and optionally of 0, said fibers being com-posed of (1) an amorphous material consisting substantially of Si, Zr and C and optionally of 0, or (2) an aggregate consisting substantially of ultrafine crystalline particles of .beta.-SiC, ZrC, a solid solution of .beta.-SiC and Zr5 and ZrC1-x wherein 0 <x< 1 and having a particle diameter of not more than 500 .ANG., in which amorphous SiO2 and ZrO2 sometimes exist in the neighborhood of these ultrafine crystalline particles, or (3) a mixture of said amorphous material (1) and said aggregate (2) of ultrafine crystalline particles. The afore-said continuous inorganic fibers can he produced by the following steps: a first step of preparing a semi-inorganic block copolymer comprising polycarbosilane blocks having a main chain skeleton composed mainly of carbosilane units of the formula ?Si-CH2?, each silicon atom of said carbosilane units having bonded thereto a side-chain group selected from the class consisting of hydrogen, lower alkyl and phenyl, and zirconoxane units of the formula ?Zr-O?; a second step of preparing a spinning dope of said semi-inorganic block copolymer and spinning the dope; a third step of subjecting the resulting fibers to a treatment of rendering them infusible under tension or under no tension; and a fourth step of firing the infusible fibers at a temperature of 800 to 1800°C in vacuum or in an atmosphere of an inert gas or a reducing gas. |
