High heat-resistant SiC-polycrystalline fiber and its fiber-bonded ceramic

摘要

Here we describe a type of SiC polycrystalline fiber (SA fiber) obtained by sintering an amorphous Si-Al-C-O fiber precursor at 1900degC in Ar atmosphere. Furthermore, we also explain a sintered SiC fiber-bonded ceramic (SA-Tyrannohex), which was synthesized by hot- pressing piled sheets of the amorphous Si-Al-C-O fiber precursor prepared from an organosilicon polymer.
