SILICON CARBIDE FIBRE AND PRODUCTION THEREOF |
摘要 |
A silicon carbide fibre, wich may have a mean crystallite size of greater than 500A, in which the silicon carbide constitutes greater than 90% by weight of the fibre, and in which the fibre is substantially homogeneous across a transverse section of the fibre The fibre may be produced by a process which comprises forming a fibre from a homogeneous mixture comprising particulate silicon carbide dispesed in a solution of an organic polymeric material in a liquid medium, and heating the fibre at elevated temperature in order to decompose the organic polymeric material and to sinter the particles of silicon carbide. |
