Thermal Performance

Identification of 3C (face-centered cubic) polytype silicon carbide from x-ray diffraction analysis, with peak broadening due to nano-crystallinity present in the fiber

The FFF SiC fiber has been exposed to high temperature environments for up to 200 hours in temperature range from 1500oC to 1650oC.  The gas environments evaluated were open air (oxygen) and argon, fed into the furnace at ambient conditions.  A thin silica layer forms on the fiber surface, less than 1 micron in thickness.
