Silicon carbide - Wikipedia

Silicon carbide fibers produced on a tungsten core of 12μm diameter show a thin interfacial layer between the silicon carbide mantle and the tungsten core, caused by chemical interaction between the silicon carbide and tungsten, which forms reaction products of α-W 2 C and W 5 Si 3. Heating above 900°C leads to growth of this reactive layer and degradation of the properties of the fiber.
