Abstract

In this work, it was systematically studied that how oxygen content of cured cobalt-containing polycarbosilance (PCS) fibers influences the structure and properties of cobalt-containing silicon carbide (Co-SiC) fibers. Compared to cured Co-PCS-air fibers, Co-PCS-O₂ fibers have a higher oxygen content and higher ceramic yield. For Co-PCS-O₂ fibers derived from cured Co-PCS-O₂, lower pyrolysis temperature was required to reach maximum mechanical properties. And higher SiC_xO_y content, higher growing speed and final sizes of β-SiC and CoSi grains and lower electrical conductivity were observed. Co-PCS-O₂ fibers have a electrical conductivity controllable between 10⁰-10³, Ω·cm and were magnetic to some degree, enabling this kind of fibers to have the potential to be used as wave-absorbing materials.
